Description:
------------
APC 3.0.8
Apache 2.0.48

Some permanently running scripts (could be called daemons) on my server crash unexpectedly (segfault Apache) after running fine for hours. Unfortunately I can't supply reproduction code as I have no clue at what point or why the script dies so I'll try to post all possible activities of that script:

- It's an RPC server
- Listens on a network socket for incoming UDP packets, possibly closes and reopens that socket
- Evaluates code fetched from a MySQL database (same code was eval'd before crash and was scheduled when crash happened)
- APC constants cache, user cache and acceleration (I just got used to it)
- Class inheritance (no new classes and no require()s in the eval'd code)
- PEAR SMTP classes and by that mail()
- Writes status information to MySQL database, including memory usage which was at about 1 MB at the time of the crash (without APC, the same script uses 5 MB btw., I guess because of compilation overhead)

Please do not comment that this should be executed via CLI :)

This may or may not be connected to Bug #6667 and probably doesn't help either.

Reproduce code:
---------------
Apache 2 is stock SUSE 9.0 Apache server, updated by YaST when security fixes were available.

PHP 5.11:

./configure
--prefix=/usr/local/php5/
--with-apxs2=/usr/sbin/apxs2
--with-openssl
--enable-safe-mode
--with-bz2
--with-zlib
--enable-magic-quotes
--enable-sockets
--with-ttf
--with-gd
--with-mysql
--with-curl
--enable-memory-limit
--enable-ftp
--enable-dbase
--with-libxml-dir=/usr/local/libxml2/



Expected result:
----------------
No segfaults.

Actual result:
--------------
Segfaults.
