Description:
------------
- apc 3.0.19
- just use apc_fetch and apc_put.. i always get a segfault with the latest cvs snapshot.. (10:30) the snapshot before 08:30 still works!
- './configure' \
'--with-pcre-regex' \
'--without-sqlite' \
'--with-mysqli=mysqlnd' \
'--with-gd' \
'--with-ttf' \
'--enable-exif' \
'--with-mcrypt' \
'--enable-mbstring' \
'--enable-spl' \
'--prefix=/usr/local/php5' \
'--with-zlib' \
'--enable-gd-native-ttf' \
'--enable-sockets' \
'--enable-soap' \
'--with-apxs2=/usr/local/apache2/bin/apxs' \
'--enable-debug' \
"$@"
- also have memcached module for php
- php.ini is not special,.. i could relevant part for apc:
extension=apc.so
apc.shm_size=128
;apc.enable_cli=1
apc.rfc1867=1
;apc.filters=NULL
;apc.enabled=1
apc.report_autofilter=1
apc.stat=1
apc.num_files_hint=100
apc.user_entries_hint=3200
apc.localcache=0
apc.localcache.size=50
apc.include_once_override=1
;apc.user_ttl = 900
;apc.ttl = 3600
apc.write_lock=1

Reproduce code:
---------------
just use apc_fetch or apc_get 

Expected result:
----------------
no segfault ;)

Actual result:
--------------

and the segfault only happens when the script is executed by apache2 (mod_php5)...
if i start php via cli .. no seg fault occures!

sorry... my fault, also happens with cli version of php..the apc.enable_cli=1 flag was missing ;)

here a backtrace from cli:

solution found, bug #7141 reported that it only works with include_once_override=0... this works for me ;)

although anyone should fix this.
