BTW, it is not the Custom 404 page php script that is causing an error,
even if I put an empty file there and name it index.php I still get the
Segmentation fault.

Also, I have no clue why there are references in this core dump to
/tmp/php-5.1.0RC1 which is the directory where I built PHP.

I just posted the core dump for the process that ended with a
Segmentation fault after trying to PUT a file in a Webdav folder.
Also, I just found out that there are many other processes ending with
a Segmentation fault, all of them happening when the server looking for
a file which is not found is trying to access a 404 custom file made in
PHP. if I change the 404 to a simple HTML everything is back to normal.
Therefore, it seems that the PHP (5.1.0RC1) is responsible for this
fault. It used to work with the previous version (5.1.0b3).

YES, that's exactly what I'm asking for and what is written in "How to report..". I'm not asking you to get the backtrace using CLI, I'm talking about mod_php/mod_dav and the only way to get their backtraces is to trace httpd (see the link Derick gave you for details). Previous Comments: [2005-09-20 22:51:28] roso at despammed dot com In fact, the problem doesn't come up when accessing a php script. Please read my report. The problem is that I cannot PUT a file in a Webdav folder after upgrading the PHP from php-5.1.0b3 to 5.1.0RC1. And the problem is replicated on two servers with PHP 5.1.0RC1 and mod_dav on Apache 2.0.54. If I --enable-debug that would help catching errors when accessing a php script, right? Maybe I need to backtrace Apache. [2005-09-20 22:35:39] [EMAIL PROTECTED] >To make a backtrace I will need PHP configured with --enable-debug. Yes.
