Subject: [perl #51092] [PATCH] Segfault when calling ->next::method on non-existing package
From: ilmari@vesla.ilmari.org (via RT) <perlbug-followup@perl.org>
Date: Thu, 21 Feb 2008 20:29:42 -0800
Message-ID: <rt-3.6.HEAD-15287-1203654581-377.51092-75-0@perl.org>

[ 33369]
Ensure that constant folding runs with IN_PERL_RUNTIME true, by copying
the current compiling cop to a different address. This ensures that
lexical hints are correctly honoured, and allows us to fold sprintf.

[ 33377]
If we have malloced_size() available, then avoid rounding up the string
to the next (guessed) plausible alignment size, and instead find out
how much memory was actually allocated, so that we can set this in the
scalar's SvLEN(). This way, sv_grow() will be called far less often.

[ 33378]
In Perl_sv_usepvn_flags(), with MYMALLOC, use the actual malloc()ed
size for SvLEN(), rather than an estimate.

[ 33379]
If the C library provides malloc_size(), we can use that in the same
places as Perl's malloced_size(), except that we need to be careful of
any PERL_TRACK_MEMPOOL manipulations in force. Wrap both as
Perl_safesysmalloc_size(), to give a consistent name and interface.

[ 33380]
Fix preprocessor syntax

[ 33383]
Comment on why I don't think changing Perl_safesysmalloc_size() in av.c
analagous to the change in sv.c is a good idea.	[It's not a language
design issue, so sadly I can't get a talk out of it. Or is that
fortunately? :-)]

[ 33389]
Add Perl_malloc_good_size to malloc.c. (A routine that rounds up the 
passed in request to the size that will actually be allocated. It's
the same interface as Darwin already provides with malloc_good_size().)

[ 33390]
Use malloc_good_size() to round up the size of requested arenas to the
size that will actually be allocated, to squeeze last few bytes into
use.
