Question Segmentation fault (11) with Debian Lenny and Apache

I have the problem that a PHP page creates a
[Fri Nov 13 13:03:26 2009] [notice] child pid 8835 exit signal Segmentation fault (11)
error in the /var/log/apache2/error.log of my Debian Lenny AMD64 installation and sometimes the browser shows an error or a blank page because of this.
I have only installed Apache2 and PHP5 for Lenny (Netinstall).
No changes made. How can I solve this problem?
Thanks in advance.

Update: I can also find
kernel: [ 2531.403329] apache2[9432]: segfault at 7fff01449640 ip 7f17db972eba sp 7fff01449620 error 6 in[7f17db6d3000+582000]
in the messages log file.

GDB (CoreDump) gives me

PHP can be brought to segfault a number of ways. I found one such bug back a few years, I don't know, if it still exists.


apache2, libphp5so, php5, segfault
