+NETaa13721: pad_findlex core dumps on bad CvOUTSIDE()
+From: Carl Witty
+Files patched: op.c sv.c toke.c
+ Each CV has a reference to the CV containing it lexically. Unfortunately,
+ it didn't reference-count this reference, so when the outer CV was freed,
+ we ended up with a pointer to memory that got reused later as some other kind
+ of SV.
+
+NETaa13721: warning suppression
+Files patched: toke.c
+ (same)
+
+NETaa13722: walk.c had inconsistent static declarations
+From: Tim Bunce
+Files patched: x2p/walk.c
+ Consolidated the various declarations and made them consistent with
+ the actual definitions.
+
+NETaa13729: order-of-evaluation dependency in scope.c on leaving REGCONTEXT
+From: "Jason Shirk"
+Files patched: scope.c
+ Did
+
+ I32 delta = SSPOPINT;
+ savestack_ix -= delta; /* regexp must have croaked */
+
+ instead.
+
+NETaa13731: couldn't assign external lexical array to itself
+From: oneill@cs.sfu.ca
+Files patched: op.c
+ The pad_findmy routine was only checking previous statements for previous
+ mention of external lexicals, so the fact that the current statement
+ already mentioned @list was not noted. It therefore allocated another
+ reference to the outside lexical, and this didn't compare equal when
+ the assigment parsing code was trying to determine whether there was a
+ common variable on either side of the equals. Since it didn't see the
+ same variable, it thought it could avoid making copies of the values on
+ the stack during list assignment. Unfortunately, before using those
+ values, the list assignment has to zero out the target array, which
+ destroys the values.
+
+ The fix was to make pad_findmy search the current statement as well. This
+ was actually a holdover from some old code that was trying to delay
+ introduction of "my" variables until the next statement. This is now
+ done with a different mechanism, so the fix should not adversely affect
+ that.
+
+NETaa13733: s/// doesn't free old string when using copy mode
+From: Larry Wall
+Files patched: pp_ctl.c pp_hot.c
+ When I removed the use of sv_replace(), I simply forgot to free the old char*.
+
+NETaa13736: closures leaked memory
+From: Carl Witty
+Files patched: op.c pp.c
+ This is a specific example of a more general bug, fixed as NETaa13760, having
+ to do with reference counts on comppads.
+
+NETaa13739: XSUB interface caches gimme in case XSUB clobbers it
+From: Dean Roehrich
+Files patched: pp_hot.c
+ Applied suggest patch. Also deleted second gimme declaration as redundant.
+
+NETaa13760: comppad reference counts were inconsistent
+From: Larry Wall
+Files patched: op.c perl.c pp_ctl.c toke.c
+ All official references to comppads are supposed to be through compcv now,
+ but the transformation was not complete, resulting in memory leakage.
+
+NETaa13761: sv_2pv() wrongly preferred IV to NV when SV was readonly
+From: "Jack R. Lawler"
+Files patched: sv.c
+ Okay, I understand how this one happened. This is a case where a
+ beneficial fix uncovered a bug elsewhere. I changed the constant
+ folder to prefer integer results over double if the numbers are the
+ same. In this case, they aren't, but it leaves the integer value there
+ anyway because the storage is already allocated for it, and it *might*
+ be used in an integer context. And since it's producing a constant, it
+ sets READONLY. Unfortunately, sv_2pv() bogusly preferred the integer
+ value to the double when READONLY was set. This never showed up if you
+ just said
+
+ print 1.4142135623731;
+
+ because in that case, there was already a string value.
+
+
+NETaa13772: shmwrite core dumps consistently
+From: Gabe Schaffer
+Files patched: opcode.h opcode.pl
+ The shmwrite operator is a list operator but neglected to push a stack
+ mark beforehand, because an 'm' was missing from opcode.pl.
+
+NETaa13773: $. was misdocumented as read-only.
+From: Inaba Hiroto
+Files patched: pod/perlvar.pod
+ <1.array-element-read-only>
+ % perl -le '$,=", "; $#w=5; for (@w) { $_=1; } print @w'
+ Modification of a read-only value attempted at -e line 1.
+ % perl4 -le '$,=", "; $#w=5; for (@w) { $_=1; } print @w'
+ 1, 1, 1, 1, 1, 1
+
+ This one may stay the way it is for performance reasons.

+ c
+ % perl -e '{ local $/ = ""; } print "$.:$_" while <>;' abc
+ 1:a
+ 2:b
+ 3:c
+
+ $/ wasn't initialized early enough, so local set it back to permanently
+ undefined on exit from the block.

+ a
+
+ % perl4 -le 'print grep(/^-/ ? ($x=$_) x 0 : 1, "a", "-b", "c");'

+
+ An extra mark was left on the stack if (('x') x $repeat) was used in a scalar
+ context.
+
+ <4.input-lineno-assign>
+ # perl -w does not complain about assignment to $. (Is this just a feature?)

+NETaa13778: -w coredumps on <$>
+From: Hans Mulder
+Files patched: pp_hot.c toke.c
+ Now produces suggested error message. Also installed guard in warning code
+ that coredumped.
+
+NETaa13779: foreach didn't use savestack mechanism
+From: Hans Mulder
+Files patched: cop.h pp_ctl.c
+ The foreach mechanism saved the old scalar value on the context stack
+ rather than the savestack. It could consequently get out of sync if
+ unexpectedly unwound.
+
+NETaa13785: GIMME sometimes used wrong context frame
+From: Greg Earle
+Files patched: embed.h global.sym op.h pp_ctl.c proto.h
+ The expression inside the return was taking its context from the immediately
+ surrounding block rather than the innermost surrounding subroutine call.
+
+NETaa13794: TieHash produces ${pack} warnings
+From: Stanley Donald Capelik x74321 24-5200 021876
+Files patched: lib/TieHash.pm
+ Changed $pack to $pkg.
+
+NETaa13797: could modify sv_undef through auto-vivification
+From: Ilya Zakharevich
+Files patched: pp.c
+ Inserted the missing check for readonly values on auto-vivification.
+
+NETaa13798: if (...) {print} treats print as quoted
+From: Larry Wall
+Files patched: toke.c
+ The trailing paren of the condition was setting expectations to XOPERATOR
+ rather than XBLOCK, so it was being treated like ${print}.
+
+NETaa13926: commonality was not detected in assignments using COND_EXPR
+From: Mark Hanson
+Files patched: opcode.h opcode.pl
+ The assignment compiler didn't check the 2nd and 3rd args of a ?:
+ for commonality. It still doesn't, but I made ?: into a "dangerous"
+ operator so it is forced to treat it as common.
+
+NETaa13957: was marking the PUSHMARK as modifiable rather than the arg
+From: David Couture
+Files patched: op.c sv.c
+ It was marking the PUSHMARK as modifiable rather than the arg.
+
+NETaa13962: documentation of behavior of scalar <*> was unclear
+From: Tom Christiansen
+Files patched: pod/perlop.pod
+ Added the following to perlop:
+
+ A glob only evaluates its (embedded) argument when it is starting a new
+ list. All values must be read before it will start over. In a list
+ context this isn't important, because you automatically get them all
+ anyway. In a scalar context, however, the operator returns the next value
+ each time it is called, or a FALSE value if you've just run out. Again,
+ FALSE is returned only once. So if you're expecting a single value from
+ a glob, it is much better to say
+
+ ($file) = <blurch*>;
+
+ than
+
+ $file = <blurch*>;
+
+ because the latter will alternate between returning a filename and
+ returning FALSE.
+
+
+NETaa13992: regexp comments not seen after + in non-extended regexp
+From: Mark Knutsen
+Files patched: regcomp.c
+ The code to skip regexp comments was guarded by a conditional that only
+ let it work when /x was in effect.
+
+NETaa14014: use subs should not count as definition, only as declaration
+From: Keith Thompson
+Files patched: sv.c
+ On *foo = \&bar, doesn't set GVf_IMPORTED if foo and bar are in same package.
+
+NETaa14021: sv_inc and sv_dec "upgraded" magical SV to non-magical
+From: Paul A Sand
+Also: Andreas Koenig
+Files patched: sv.c
+ The sv_inc() and sv_dec() routines "upgraded" null magical SVs to non-magical.
+
+NETaa14086: require should check tainting
+From: Karl Simon Berg
+Files patched: pp_ctl.c
+ Since we shouldn't allow tainted requires anyway, it now says:
+
+ Insecure dependency in require while running with -T switch at tst.pl line 1.
+
+NETaa14104: negation fails on magical variables like $1
+From: tim
+Files patched: pp.c
+ Negation was failing on magical values like $1. It was testing the wrong
+ bits and also failed to provide a final "else" if none of the bits matched.
+
+NETaa14107: deep sort return leaked contexts
+From: Quentin Fennessy
+Files patched: pp_ctl.c
+ Needed to call dounwind() appropriately.
+
+NETaa14129: attempt to localize via a reference core dumps
+From: Michele Sardo
+Files patched: op.c pod/perldiag.pod
+ Now produces an error "Can't localize a reference", with explanation in
+ perldiag.
+
+NETaa14138: substr() and s/// can cause core dump
+From: Andrew Vignaux
+Files patched: pp_hot.c
+ Forgot to call SvOOK_off() on the SV before freeing its string.
+
+NETaa14145: ${@INC}[0] dumped core in debugger
+From: Hans Mulder
+Files patched: sv.c
+ Now croaks "Bizarre copy of ARRAY in block exit", which is better than
+ a core dump. The fact that ${@INC}[0] means $INC[0] outside the debugger
+ is a different bug.
+
+NETaa14147: bitwise assignment ops wipe out byte of target string
+From: Jim Richardson
+Files patched: doop.c
+ The code was assuming that the target was not either of the two operands,
+ which is false for an assignment operator.
+
+NETaa14153: lexing of lexicals in patterns fooled by character class
+From: Dave Bianchi
+Files patched: toke.c
+ It never called the dwimmer, which is how it fooled it.
+
+NETaa14154: allowed autoloaded methods by recognizing sub method; declaration
+From: Larry Wall
+Files patched: gv.c
+ Made sub method declaration sufficient for autoloader to stop searching on.
+
+NETaa14156: shouldn't optimize block scope on tainting
+From: Pete Peterson
+Files patched: op.c toke.c
+ I totally disabled the block scope optimization when running tainted.
+
+NETaa14157: -T and -B only allowed 1/30 "odd" characters--changed to 1/3
+From: Tor Lillqvist
+Files patched: pp_sys.c
+ Applied suggested patch.
+
+NETaa14160: deref of null symbol should produce null list
+From: Jared Rhine
+Files patched: pp_hot.c
+ It didn't check for list context before returning undef.
+
+NETaa14162: POSIX::gensym now returns a symbol reference
+From: Josh N. Pritikin
+Also: Tim Bunce
+Files patched: ext/POSIX/POSIX.pm
+ Applied suggested patch.
+
+NETaa14164: POSIX autoloader now distinguishes non-constant "constants"
+From: Tim Bunce <Tim.Bunce@ig.co.uk>
+Files patched: ext/POSIX/POSIX.pm ext/POSIX/POSIX.xs
+ The .xs file now distinguishes non-constant "constants" by setting EAGAIN.
+ This will also let us use #ifdef within the .xs file to de-constantify
+ any other macros that happen not to be constants even if they don't use
+ an argument.
+
+NETaa14166: missing semicolon after "my" induces core dump
+From: Thomas Kofler
+Files patched: toke.c
+ The parser was left thinking it was still processing a "my", and flubbed.
+ I made it wipe out the "in_my" variable on a syntax error.
+
+NETaa14166: missing semicolon after "my" induces core dump"
+Files patched: toke.c
+ (same)
+
+NETaa14206: can now use English and strict at the same time
+From: Andrew Wilcox
+Files patched: sv.c
+ It now counts imported symbols as okay under "use strict".
+
+NETaa14206: can now use English and strict at the same time
+Files patched: gv.c pod/perldiag.pod

+
+NETaa14265: elseif now produces severe warning
+From: Yutao Feng
+Files patched: pod/perldiag.pod toke.c
+ Now complains explicitly about "elseif".
+
+NETaa14279: list assignment propagated taintedness to independent scalars
+From: Tim Freeman
+Files patched: pp_hot.c
+ List assignment needed to be modified so that tainting didn't propagate
+ between independent scalar values.
+
+NETaa14312: undef in @EXPORTS core dumps
+From: William Setzer
+Files patched: lib/Exporter.pm
+ Now says:
+
+ Unable to create sub named "t::" at lib/Exporter.pm line 159.
+ Illegal null symbol in @t::EXPORT at -e line 1
+ BEGIN failed--compilation aborted at -e line 1.
+
+
+NETaa14312: undef in @EXPORTS core dumps
+Files patched: pod/perldiag.pod sv.c
+ (same)
+
+NETaa14321: literal @array check shouldn't happen inside embedded expressions
+From: Mark H. Nodine
+Files patched: toke.c
+ The general solution to this is to disable the literal @array check within
+ any embedded expression. For instance, this also failed bogusly:
+
+ print "$foo{@foo}";
+
+ The reason fixing this also fixes the s///e problem is that the lexer
+ effectively puts the RHS into a do {} block, making the expression
+ embedded within curlies, as far as the error message is concerned.
+
+NETaa14322: now localizes $! during POSIX::AUTOLOAD
+From: Larry Wall
+Files patched: ext/POSIX/POSIX.pm
+ Added local $! = 0.
+
+NETaa14324: defined() causes spurious sub existence
+From: "Andreas Koenig"
+Files patched: op.c pp.c
+ It called pp_rv2cv which wrongly assumed it could add any sub it referenced.
+
+NETaa14336: use Module () forces import of nothing
+From: Tim Bunce
+Files patched: op.c

+ From: lwall@scalpel.netlabs.com (Larry Wall)
+
+ : No. Larry's currently got the patch pumpkin for all such core perl topics.
+
+ I dunno whether you should let me have the patch pumpkin or not. To fix
+ a Sev 2 I just hacked in rudimentary prototypes. :-)
+
+ We can now define true unary subroutines, as well as argumentless
+ subroutines:
+
+ sub baz () { 12; } # Must not have argument
+ sub bar ($) { $_[0] * 7 } # Must have exactly one argument
+ sub foo ($@) { print "@_\n" } # Must have at least one argument
+ foo bar baz / 2 || "oops", "is the answer";
+
+ This prints "42 is the answer" on my machine. That is, it's the same as
+
+ foo( bar( baz() / 2) || "oops", "is the answer");
+
+ Attempting to compile
+
+ foo;
+
+ results in
+
+ Too few arguments for main::foo at ./try line 8, near "foo;"
+
+ Compiling
+
+ bar 1,2,3;
+
+ results in
+
+ Too many arguments for main::bar at ./try line 8, near "foo;"
+
+ But
+
+ @array = ('a','b','c');
+ foo @array, @array;
+
+ prints "3 a b c" because the $ puts the first arg of foo into scalar context.
+
+ The main win at this point is that we can say
+
+ sub AAA () { 1; }
+ sub BBB () { 2; }
+
+ and the user can say AAA + BBB and get 3.
+
+ I'm not quite sure how this interacts with autoloading though. I fear
+ POSIX.pm will need to say
+
+ sub E2BIG ();
+ sub EACCES ();
+ sub EAGAIN ();
+ sub EBADF ();
+ sub EBUSY ();
+ ...
+ sub _SC_STREAM_MAX ();
+ sub _SC_TZNAME_MAX ();
+ sub _SC_VERSION ();
+
+ unless we can figure out how to efficiently declare a default prototype
+ at import time. Meaning, not using eval. Currently
+
+ *foo = \&bar;
+
+ (the ordinary import mechanism) implicitly stubs &bar with no prototype if
+ &bar is not yet declared. It's almost like you want an AUTOPROTO to
+ go with your AUTOLOAD.
+
+ Another thing to rub one's 5 o'clock shadow over is that there's no way
+ to apply a prototype to a method call at compile time.
+
+ And no, I don't want to have the
+
+ sub howabout ($formal, @arguments) { ... }
+
+ argument right now.

+NETaa14444: lexical scalar didn't autovivify
+From: Gurusamy Sarathy
+Files patched: op.c pp_hot.c
+ It didn't have code in pp_padsv to do the right thing.
+
+NETaa14448: caller could dump core when used within an eval or require
+From: Danny R. Faught
+Files patched: pp_ctl.c
+ caller() was incorrectly assuming the context stack contained a subroutine
+ context when it in fact contained an eval context.
+
+NETaa14451: improved error message on bad pipe filehandle
+From: Danny R. Faught
+Files patched: pp_sys.c
+ Now says the slightly more informative
+
+ Can't use an undefined value as filehandle reference at ./try line 3.
+
+NETaa14462: pp_dbstate had a scope leakage on recursion suppression
+From: Tim Bunce
+Files patched: pp_ctl.c
+ Swapped the code in question around.
+
+NETaa14482: sv_unref freed ref prematurely at times
+From: Gurusamy Sarathy
+Files patched: sv.c
+ Made sv_unref() mortalize rather than free the old reference.
+
+NETaa14484: appending string to array produced bizarre results
+From: Greg Ward
+Also: Malcolm Beattie
+Files patched: pp_hot.c
+ Will now say, "Can't coerce ARRAY to string".
+
+NETaa14525: assignment to globs didn't reset them correctly
+From: Gurusamy Sarathy
+Files patched: sv.c
+ Applied parts of patch not overridden by subsequent patch.
+
+NETaa14529: a partially matching subpattern could spoof infinity detector
+From: Wayne Berke
+Files patched: regexec.c
+ A partial match on a subpattern could fool the infinite regress detector
+ into thinking progress had been made.
+ The previous workaround prevented another bug (NETaa14529) from being fixed,
+ so I've backed it out. I'll need to think more about how to detect failure
+ to progress. I'm still hopeful it's not equivalent to the halting problem.
+
+NETaa14535: patches from Gurusamy Sarathy
+From: Gurusamy Sarathy
+Files patched: op.c pp.c pp_hot.c regexec.c sv.c toke.c
+ Applied most recent suggested patches.
+
+NETaa14538: method calls were treated like do {} under loop modifiers
+From: Ilya Zakharevich
+Files patched: perly.c perly.y
+ Needed to take the OPf_SPECIAL flag off of entersubs from method reductions.
+ (It was probably a cut-and-paste error from long ago.)
+
+NETaa14540: foreach (@array) no longer does extra stack copy
+From: darrinm@lmc.com
+Files patched: Todo op.c pp_ctl.c pp_hot.c
+ Fixed by doing the foreach(@array) optimization, so it iterates

+
+NETaa14548: magic sets didn't check private OK bits

+NETaa14581: shouldn't execute BEGIN when there are compilation errors
+From: Rickard Westman
+Files patched: op.c
+ Perl should not try to execute BEGIN and END blocks if there's been a
+ compilation error.
+
+NETaa14582: got SEGV sorting sparse array
+From: Rick Pluta
+Files patched: pp_ctl.c
+ Now weeds out undefined values much like Perl 4 did.

+NETaa14614: now does dbmopen with perl_eval_sv()

+NETaa14639: (?i) didn't reset on runtime patterns

+NETaa14649: selecting anonymous globs dumps core
+From: Chip Salzenberg
+Files patched: cop.h doio.c embed.h global.sym perl.c pp_sys.c proto.h
+ Applied suggested patch, but reversed the increment and decrement to avoid

+NETaa14668: {2,} could match once
+From: Hugo van der Sanden

+
+NETaa14673: open $undefined dumped core
+From: Samuli K{rkk{inen
+Files patched: pp_sys.c
+ pp_open() didn't check its argument for globness.
+
+NETaa14683: stringifies were running pad out of space
+From: Robin Barker
+Files patched: op.h toke.c
+ Increased PADOFFSET to a U32, and made lexer not put double-quoted strings
+ inside OP_STRINGIFY unless they really needed it.
+
+NETaa14689: shouldn't have . in @INC when tainting
+From: William R. Somsky
+Files patched: perl.c
+ Now does not put . into @INC when tainting. It may still be added with a
+
+ use lib ".";
+
+ or, to put it at the end,
+
+ BEGIN { push(@INC, ".") }
+
+ but this is not recommended unless a chdir to a known location has been done
+ first.
+
+NETaa14690: values inside tainted SVs were ignored
+From: "James M. Stern"
+Files patched: pp.c pp_ctl.c
+ It was assuming that a tainted value was a string.
+
+NETaa14692: format name required qualification under use strict
+From: Tom Christiansen
+Files patched: gv.c
+ Now treats format names the same as subroutine names.
+
+NETaa14695: added simple regexp caching
+From: John Rowe
+Files patched: pp_ctl.c
+ Applied suggested patch.
+
+NETaa14697: regexp comments were sometimes wrongly treated as literal text
+From: Tom Christiansen
+Files patched: regcomp.c
+ The literal-character grabber didn't know about extended comments.
+
+ (By the way, Tom, the boxed form of quoting in the previous enclosure is
+ exceeding antisocial when you want to extract the code from it.)
+
+NETaa14704: closure got wrong outer scope if outer sub was predeclared
+From: Marc Paquette
+Files patched: op.c
+ The outer scope of the anonymous sub was set to the stub rather than to
+ the actual subroutine. I kludged it by making the outer scope of the
+ stub be the actual subroutine, if anything is depending on the stub.
+
+NETaa14705: $foo .= $foo did free memory read
+From: Gerd Knops
+Files patched: sv.c
+ Now modifies address to copy if it was reallocated.
+
+NETaa14711: added (&) and (*) prototypes for blocks and symbols
+From: Kenneth Albanowski
+Files patched: Makefile.SH op.c perly.c perly.h perly.y toke.c
+ & now means that it must have an anonymous sub as that argument. If
+ it's the first argument, the sub may be specified as a block in the
+ indirect object slot, much like grep or sort, which have prototypes of (&@).
+
+ Also added * so you can do things like
+
+ sub myopen (*;$);
+
+ myopen(FOO, $filename);
+
+NETaa14713: setuid FROM root now defaults to not do tainting
+From: Tony Camas
+Files patched: mg.c perl.c pp_hot.c
+ Applied suggested patch.
+
+NETaa14714: duplicate magics could be added to an SV
+From: Yary Hluchan
+Files patched: sv.c sv.c
+ The sv_magic() routine didn't properly check to see if it already had a
+ magic of that type. Ordinarily it would have, but it was called during
+ mg_get(), which forces the magic flags off temporarily.
+
+NETaa14734: ref should never return undef
+From: Dale Amon
+Files patched: pp.c t/op/overload.t
+ Now returns null string.
+
+NETaa14751: slice of undefs now returns null list

+
+NETaa14845: s/// didn't handle offset strings
+From: Ken MacLeod

+
+NETaa14851: Use of << to mean <<"" is deprecated
+From: Larry Wall
+Files patched: toke.c
+
+NETaa14865: added HINT_BLOCK_SCOPE to "elsif"
+From: Jim Avera
+Files patched: perly.y
+ Needed to set HINT_BLOCK_SCOPE on "elsif" to prevent the do block from
+ being optimized away, which caused the statement transition in elsif
+ to reset the stack too far back.
+
+NETaa14876: couldn't delete localized GV safely
+From: John Hughes
+Files patched: pp.c scope.c
+ The reference count of the "borrowed" GV needed to be incremented while
+ there was a reference to it in the savestack.
+
+NETaa14887: couldn't negate magical scalars
+From: ian
+Also: Gurusamy Sarathy
+Files patched: pp.c
+ Applied suggested patch, more or less. (It's not necessary to test both

+
+NETaa14893: /m modifier was sticky
+From: Jim Avera
+Files patched: pp_ctl.c
+ pp_match() and pp_subst() were using an improperly scoped SAVEINT to restore
+ the value of the internal variable multiline.
+
+NETaa14893: /m modifier was sticky
