Before this backtrace, GDB should have spit out an error too with a
source line, can you please paste that one in the form, and also the
result of:
print data
and
print sd
(at the same place as were you typed 'bt').
thanks!

While trying to backtrace a particular forked child it would not
segfault until i detach gdb from it - then it segfaults with:
[Sat Dec 14 05:02:19 2002] [notice] child pid 4858 exit signal
Segmentation fault (11)

I know it's not a backtrace. I have just forgot to paste apache log
segfault line example in my original posting.
However. When trying to backtrace I cannot reproduce this
behavior. It's happening under constant heavy load that
can be simulated using ab -n 10000 and the example script
I have supplied. Only after about 3000-4000 request this
one happens. I cannot execute 3000 request because httpd -X
exits after several hundred requests (normal exit - no backtrace) and I
don't know why.
