[imp] Seg Faulting.. sigh

[Jeremy Freeman]

I posted earlier about my Apache randomly segfaulting for unknown 
reasons. I have finally managed to capture a backtrace of the event and 
was _hoping_ someone out there could provide some insight into the problem.

I am Running:

Apache/1.3.26 (Unix) with
PHP/4.2.2
mod_perl/1.27
mod_ssl/2.8.10 OpenSSL/0.9.6e

PHP compiled with: './configure' '--with-mysql' 
'--with-apache=../apache_1.3.26/' '--enable-debug' '--with-gettext' 
'--with-imap=../imap-2002.RC2/' '--with-xml'

All compiled in static.

Kernel: Linux 2.2.19pre17

Here is the backtrace:

Starting program: /usr/local/src/apache_1.3.26/src/httpd -X -DSSL

Program received signal SIGSEGV, Segmentation fault.
