* Use of freed comppad array during clear_yystack()Marcus Holland-Moritz2009-07-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Message-ID: <20081026231720.34258457@r2d2> Patch description from the original email : I tried to make tests pass on a perl built with -DPERL_POISON, as some tests were dying with segfaults. They all originated from the same source: clear_yystack() after a compile error. [...] As far as I can see, after croaking the newly created CV is destroyed and its pad is undef'd. [...] This will SvREFCNT_dec PL_comppad and set PL_comppad to NULL. However, later, in clear_yystack(), when the ops are freed, the old PL_comppad is restored by PAD_RESTORE_LOCAL, as a reference is still in ps->comppad. But now the pad AV is already dead. Normally (i.e. without PERL_POISON), the dead AV will have AvARRAY(av) set to NULL by av_undef(). So PAD_RESTORE_LOCAL will actually set PL_curpad to NULL, and thus pad_free() will not attempt to do anything. But with PERL_POISON, the storage for AvARRAY(av) (i.e. sv_u) will be reused for chaining the free SV heads in the arena (as opposed to SvANY(sv) in case of !PERL_POISON). This means that PAD_RESTORE_LOCAL will find AvARRAY(av) non-NULL and will set PL_curpad to that value, finally causing the segfault in pad_free(). While I think I understand what's going on, I don't have the slightest clue how to properly fix this. Given that it's not a problem only under PERL_POISON, but always (as dead SV heads are being used), I think it should ultimately be fixed. The only thing I can offer right now is a patch to make it work with PERL_POISON as good (or as bad) as without by making PAD_RESTORE_LOCAL explicitly check if the pad passed in is already dead and refusing to use it if it is.

* Add a macro MUTABLE_PTR(p), which on (non-pedantic) gcc will not castNicholas Clark2009-03-291-8/+8
| | | | | | | | | | | | | away const, returning a void *. Add MUTABLE_SV(sv) which uses this, and replace all (SV *) casts either with MUTABLE_SV(sv), or (const SV *). This probably still needs some work - assigning to SvPVX() and SvRV() is now likely to generate a casting error. The core doesn't do this. But as-is it's finding bugs that can be fixed. p4raw-id: //depot/perl@34605 (cherry-picked from commit b1bc3f345d4dfe19cd94c120c46649336b5cb92b)
