I know it was fixed, but I just thought I'ld add that the problem has started
producing itself in the new copy of httpd that I compiled, strange that it took a
while before it started occurring.
Starting program: /opt/server/httpd/bin/httpd -X
(no debugging symbols found)...
Program received signal SIGSEGV, Segmentation fault.

Well I recompiled with --enable-debug to do as you said, and it now seems to work and
doesn't crash.
This was with EXACTLY the same options as the first time when it didn't work (except
--enable-debug). I guess I can only put it down to RedHat 7.0, not the best of
releases, we intend to upgrade it as soon as we get a chance.
Thanks for your time anyway.

Can you compile PHP with --enable-debug, and create a new backtrace? THis gives us
more information (you can do a
'bt full' too, which fives even more useful information.
