I have a page that is generating repeated segmentation faults on a
Redhat 8 system running Apache 1.3.27 and PHP 4.3.1. It is part of a
forum system (FudForum) that, unforunately, I didn't write. MySQL and
sessions are both involved. The faults are not occurring on every use,
but seem to occur about once an hour. Once a seg fault appears I tend
to see 4-5 of them in succession, then they disappear again for an hour
or so.

Segmentation fault (11)
I was able to generate a backtrace by running httpd -X in gdb.
(gdb) run -X
Starting program: /usr/local/apache/bin/httpd -X
Program received signal SIGSEGV, Segmentation fault.

GCC Version: gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
My php config is VERY simple:
./configure \
--with-apxs=/usr/local/apache/bin/apxs \
--with-mysql \
--with-pgsql \
--with-pspell \
--enable-debug
I'm sure there is a great deal of additional information I can provide,
and I will do so quite willingly. My apologies if I've overlooked
anything in this report.
