Don't recurse into op_size() on op->pmnext.
It doesn't point to an OP owned by the current OP - it is used to form a linked

end up pointing to freed memory, which results in much jollity.

eval $ExtUtils::MakeMaker::VERSION to avoid warnings about _ not being numeric.

Skip the aelemfast size comparison test for perls which predate the code change.
It was merged to maint-5.8 between 5.8.3 and 5.8.4, so 5.8.4 and later have it.
For 5.8.3 and earlier, the assumptions the test makes about sizes (based on op
structure) are bogus.
Nicholas Clark [Sun, 1 May 2011 21:02:59 +0000]

Probably better to slightly under report sizes, than report something random or
SEGV.

Set the pointer alignment (in bits) via a C macro generated by the Makefile.PL
The previous approach of using sizeof(void *) is flat out wrong on a 64 bit
system. The right answer is 3. It gives 4. Which isn't a problem once the
pointer rotation code in check_new() isn't buggy, but isn't as efficient as
desired.
Nicholas Clark [Sun, 1 May 2011 19:56:48 +0000]
Fix typo error in bit-vector tracking mechanism, causing bogus "seen before"s.
On 64 bit platforms which allocate on 8 byte alignment (rather than 16), a low

"seen". Joy, hilarity, failing tests and different results running under gdb.

total_size() and size() can be XS ALIASes, now all the logic is in sv_size()
Nicholas Clark [Sun, 24 Apr 2011 20:51:52 +0000]
Move iteration over array values from total_size() to sv_size()
For now this requires some bodgery over when array values should be recursed
into. Arrays presented to total_size() should be properly recursed into.
However, historically the inner arrays of padlists were never traversed, which
means there is no code to deal with the special case rules for them. So to avoid
the perfect being the enemy of the good, defer writing that code, by skipping
the inner arrays of padlists for now.
Nicholas Clark [Sun, 24 Apr 2011 20:39:18 +0000]
Handle sizes for PVGVs in sv_size() only.
Previously the logic was duplicated in total_size().
Nicholas Clark [Sun, 24 Apr 2011 15:32:40 +0000]
Move iteration over hash values from total_size() to sv_size()
For now this requires some bodgery over when hash values should be recursed
into. Hashes presented to total_size() should be properly recursed into, else
the size of symbol tables isn't correctly reported. However, the back-link
from a CV to its stash shouldn't be traversed, as shouldn't GVs referenced from
OPs, else we run the risk of passing through %::, and adding the size of all
the symbol tables (and subroutines) to the size of a subroutine reference we
were directly passed. Whilst this might be useful in some cases, it isn't useful
as a default, and it isn't even vaguely consistent with the sizes total_size()
historically reported.
Nicholas Clark [Sun, 24 Apr 2011 19:45:25 +0000]
Fix potential SEGVs for PVBMs on 5.10.0 and later.
5.10.0 stores PVBMs as PVGVs. Hence not all PVGVs are typeglobs, and XS code
should check isGV_with_GP() is true before performing typeglob lookups.
The PVGV code currently ignores SvCUR()/SvLEN(), so for now the size of PVBMs
is under-reported on 5.10.0 and later.
Nicholas Clark [Sun, 24 Apr 2011 17:43:32 +0000]
The optree holds pointers to GVs under multiplicity. It's ithreads that differs.
Hence the tests that are conditional on the different behaviours should be
{unthreaded,multiplicity} vs {ithreads}, not
{unthreaded} vs {multiplicity,ithreads}
Nicholas Clark [Sat, 23 Apr 2011 20:55:48 +0000]
In op_size, add break statement missing for OPc_PVOP.
This has been missing since op_size was added in 0.60. Without it, PVOPs would
run on into the OPc_LOOP case, which would likely SEGV as it would consider
the char *op_pv as OP *op_first, and non-existent op_last, op_redoop, op_nextop
and op_lastop.
Nicholas Clark [Sat, 23 Apr 2011 20:07:10 +0000]
Fix potential SEGVs for OP_AELEMFAST on a lexical.
OP_AELEMFAST is wonderfully special, in that it can be used to replace both
OP_GV and OP_PADAV. The latter is only a baseop, whereas OP_AELEMFAST is a
flagged as a padop/svop. baseops are smaller, and (therefore) don't have memory
allocated where op_sv "should" be.
