thanks for your advice, this is the backtrace I've got:

2.4.4, etc.

Your last statement could easily lead to the assumption that your local
regexp implementation/library is broken.
To produce a backtrace on apache, fire up gdb with the apache binary
and start with the parameter '-X'.

The crash don't happen when php is runing as a cgi or with the cli api.
And I have no idea how to tell the apache to dump a core when the
php-module crashes. So I'm not able to provide a backtrace.
This is the configure I've used:
'./configure' '--prefix=/usr/local' '--with-config-file-path=/etc'
'--with-apxs=/usr/local/apache/bin/apxs' '--enable-shared'
'--enable-sysvsem' '--enable-sysvshm' '--enable-inline-optimization'
'--with-regex=system' '--with-mysql=/usr/local/mysql'
'--with-interbase=/opt/interbase' '--enable-ftp' '--enable-sockets'
'--with-zlib-dir=/usr/local' '--with-ttf' '--with-png-dir=/usr/local'
'--with-gd=/usr/local' '--with-jpeg-dir=/usr/local' '--with-gettext'
'--with-pdflib'
If I use '--with-regex=php' instead of 'system' everything works fine.

I can not reproduce this with latest CVS or with 4.2.0RC2.
Please add the configure line used into this bug report.
Also, configure php with --enable-debug and generate
a GDB backtrace of the crash.

this line crashes the apache process with php 4.2.0RC2 as a module
<?php
if (ereg('foo', 'string with foo')) echo 'got it';
?>
