Apache - SIGSEGV but no core dumps.

[Przemyslaw Wegrzyn <czajnik@tower.t16.ds.pwr.wroc.pl>]

Hello !

I have noticed the following lines in Apache's error.log:

[Fri Jun 29 17:35:41 2001] [notice] child pid 18786 exit signal
Segmentation fault (11)
[Fri Jun 29 17:35:54 2001] [notice] child pid 20229 exit signal
Segmentation fault (11)

I've strace'd Apache - the child processes dies after finishing handling
request and writing line to access log , so it isn't critical, but... 

I use Apache 1.3.19 + php4.0.5 from Woody in chrooted enviroment. 
My problem is actually I can't force Apache to drop core files.
I've added ulimit -c unlimited to /etc/init.d/apache, and set 
CoreDumpDirectory to some world writeable dir. 
Nope - I can't get any core to do backtrace on it. Why ?
