 Bug Type:         Reproducible crash
 Operating System: Mandriva Linux (Cooker x86_64)
 PHP Version:      5.3.1RC2
 New Comment:

We now have about three weeks of successful operation with
zend.enable_gc = Off

I assume it is safe to say that this bug indeed is GC related.

I switched the gc off, will provide feedback in about a week.

Does this happen with gc turned off?

Try adding:

zend.enable_gc = Off

to your php.ini file.

We're affected with the same bug - 5.3.1, Fedora Core 8, 32bit, Apache
2.2.6.

This happens suddenly after few days of normal operation - then some of
the Apache requests end up with $this not defined inside an object
instance. Normal operation is resumed after Apache is restarted.

We never encountered this problem on 5.3.0 (used for over a month),
though I am not saying its not there as lots of our code changed
meanwhile as well.

(Hopefully this will not reset the Feedback status).

I've tried this on a similar i586 machine and cannot reproduce the
problem, this leads me to believe the problem is indeed x86_64 related.
I will try and obtain access to another x86_64 machine to reproduce the
problem there too.

If the bug status changes, please put it back to Feedback.
