Please provide a way to reproduce this problem (aka not randomly). That means
to
debug a little bit to see what happens in your app while it crashes. using
vBulletin as a base to fix such crashes is not an option for us.
Thanks for your understanding,

OK, closed now. You can still reopen it if it happens again

Thanks for all your help.
The segfault isnt reproducable now.
Maybe the last vBulletin Board update changes some thing in the Object handling
or maybe i have updated some librarys.
I have tested with PHP-FPM 5.3.6 and the latest Snapshot.
So i think you can close this bugreport.
Greets,
Daniel

Valgrind log would be quite helpful:

I've asked for help on internals: http://news.php.net/php.internals/53922
see where it goes
