Try to compile without --enable-debug and use the valgrind tool, like

valgrind /path/to/apachecesource/src/httpd -X
(causes valgrind to start apache in single process mode)

Then request the script that crashes. Valgrind should spit out some
information about wrong memory usage. If you can get that information to
me, and perhaps with the accompaying script (shorter == better) I'm
pretty sure I can fix the problem.
