Description:
------------
I am afraid that I don't have the actual PHP code at short hand.
However, Apache segfaults when I try to log into my Horde Webmail application (running 5.12). After
the segfault I cannot login any more and I get a blank page and sometimes an 500 error message
shown. Restarting the webserver helps, but after logout and relogin the problem persists.
This problem exists at least since PHP 5.4.20 because thats the version I have started with. I
don't know if this problem/bug exists also in previous 5.4 versions.
Upgrading to 5.5.4 solved my problems, but I would rather like to stick to 5.4
Actual result:
--------------
(gdb) run -DSSL -X -f /etc/httpd/conf/httpd.conf
