Description:
------------
Using PHP 5.2.6, Apache 2.0.63 on Solaris 10 (SPARC) with APC 3.1.2 not beta.

When APC cache has but a few kbytes left, Apache processes core dump.  Increasing cache size helps, but that's a nervous fix. 

Here's my php.ini settings relevant to APC:
extension="apc.so"
apc.enabled="1"
apc.shm_segments="1"
apc.shm_size="60"
apc.localcache="1"
apc.localcache.size="1024"
apc.ttl="3600"
apc.user_ttl="3600"
apc.include_once_override="1"

I built APC with these options:
'--enable-apc' \
'--enable-apc-mmap' \
'--with-apxs' \
'--enable-apc-sem' \
'--with-php-config=/usr/local/php-5.2.6/bin/php-config' \

Reproduce code:
---------------
No particular code, but when the opcode cache gets full for us it segfaults each Apache child.
