Crash with PHP, Apache and mod_perl

Hello, I have a problem getting my Apache server to work with PHP and mod_perl at the same time. My Apache 1.3.12 server using mod_perl 1.24 (compiled into the Apache executable) and PHP 4.0.2 as a dynamic module (.so) crashes as soon as I access it. For example, "lynx localhost" reports "unexpected network errors", and then quits. Netscape just reports that the document is empty. If I rebuild Apache and leave out mod_perl (but do load PHP), everything is fine. If I leave mod_perl in but don't load the PHP module (i.e., comment out the line in httpd.conf) everything is fine as well (except I don't have PHP). If I check /usr/local/apache/logs/error_log, it says: "Apache/1.3.12 (Unix) PHP/4.0.2 mod_perl/1.24 configured -- resuming normal operations". As soon as I access the server, a new line is added: "child pid nnn exit signal Segmentation fault (11)" PHP build was configured with: ./configure --with-mysql=/usr/local --with-apxs=/usr/local/apache/bin/apxs No warnings at the end (i.e. no warning about e.g. a corrupted apxs script) Built with just: make , followed by: make install The php.ini file was just copied and renamed from php.ini-dist Apache 1.3.12 was compiled with all default modules, with mod_so and mod_perl added. The only thing I changed in httpd.conf is the server name, which is set to 'www'. mod_perl is version 1.24, built without any special options. I use mysql 3.22.32. No additional options during build, just configure, make, make install. For some technical bits, here's the gdb backtrack output: #0 0x4039023a in ??

I have checked the bugbase at bugs.php.net as well, but to no avail. If you need any more information, please contact me via e-mail. Ruud.
