The segfault is after exit() is called, when libc is cleaning up things. I guess something has corrupted some internal libc/ld-linux.so data structures, but I have no idea what has caused it.

There are similar problems described at

http://pecl.php.net/bugs/bug.php?id=10253 http://www.forum.psoft.net/archive/index.php/t-17149.html

In both cases they could be fixed by disabling php extensions (mnogosearch, apc). Maybe you try disabling php extensions you don't absolutely need. Especially those that do not come from Debian (if any).
