Description of problem:
I attached to a httpd child process with gdb and waited for it to crash. That's
on a site with php and postgresql. I'm using the potsgresql 7.1.3 rpms and php
built form the spec file with --with-mcrypt added and CFLAGS changed to include -g.

Program received signal SIGSEGV, Segmentation fault.
