Hello Sander,
This email contains the print out from your first request. I'll work on
your second request and post results in a later email.
Here's the backtrace:

Two requests:
1) could you send a backtrace (bt) taken after the segfault and
2) try this on a copy of Apache compiled with debug symbols:
CFLAGS="-DDEBUG -O0"; export CFLAGS
./configure --prefix=/somewhere (...) --enable-maintainer-mode (...)
make
make install
You don't seem to get far enough for Apache to fork() its child processes, but
if you want to prevent forking you can tell gdb to
run -X
Thanks,
S.
