Bug#753851: Backtrace obtained
Hello,
I obtained now a backtrace.
I had to include the ulimit into the apache2 init.d script:
root@home:/etc/init.d# diff apache2.orig apache2
172a173
> ulimit -c unlimited
root@home:/etc/init.d#
It seems to be a php5 issue:
root@home:/var/cache/apache2# gdb /usr/sbin/apache2 /var/cache/apache2/core

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
(gdb)
The problem showed up with (5.6.0~rc1+dfsg-1), upgraded now to
5.6.0~rc2+dfsg-1 from sid and check if the problem will be reproduced there as
well.
Thanks,
Rainer
