-=head1 KNOWN PROBLEMS
-
-This section outlines all known problems that exist in the
-I<call_*> functions.
-
-=over 5
-
-=item 1.
-
-If you are intending to make use of both the G_EVAL and G_SCALAR flags
-in your code, use a version of Perl greater than 5.000.  There is a bug
-in version 5.000 of Perl which means that the combination of these two
-flags will not work as described in the section I<FLAG VALUES>.
-
-Specifically, if the two flags are used when calling a subroutine and
-that subroutine does not call I<die>, the value returned by
-I<call_*> will be wrong.
-
-
-=item 2.
-
-In Perl 5.000 and 5.001 there is a problem with using I<call_*> if
-the Perl sub you are calling attempts to trap a I<die>.
-
-The symptom of this problem is that the called Perl sub will continue
-to completion, but whenever it attempts to pass control back to the
-XSUB, the program will immediately terminate.
-
-For example, say you want to call this Perl sub
-
-    sub fred
-    {
-        eval { die "Fatal Error" ; }
-        print "Trapped error: $@\n"
-            if $@ ;
-    }
-
-via this XSUB
-
-    void
-    Call_fred()
-        CODE:
-        PUSHMARK(SP) ;
-        call_pv("fred", G_DISCARD|G_NOARGS) ;
-        fprintf(stderr, "back in Call_fred\n") ;
-
-When C<Call_fred> is executed it will print
-
-    Trapped error: Fatal Error
-
-As control never returns to C<Call_fred>, the C<"back in Call_fred">
-string will not get printed.
-
-To work around this problem, you can either upgrade to Perl 5.002 or
-higher, or use the G_EVAL flag with I<call_*> as shown below
-
-    void
-    Call_fred()
-        CODE:
-        PUSHMARK(SP) ;
-        call_pv("fred", G_EVAL|G_DISCARD|G_NOARGS) ;
-        fprintf(stderr, "back in Call_fred\n") ;
