Hello Stefan,

Thank you very much to pointing that out, I'm not a programmer, as I 
already mentioned, but I tried to get apache core-dumps before starting 
this bug-report, and I get some, but unfortunately with apache compiled 
without debug symbols.

I simply don't know how to get core-dumps out of these segmentation 
faults again. Maybe you can help me to get some core-dumps out of these 
segfaults?
I used mod_prctl.c to get core-dumps:

The gdb issue might came from the kernel my vserver uses, I don't know.
