When I run .php files under Apache (1.3.19) PHP sometimes crash. I can run the same file several times, and only sometimes is crashes PHP. I have found out that it only happens when the PHP file is accessing a MySQL database.

This is what is recorded in the apache log (a lot of them):

[Fri Mar  9 19:24:51 2001] [notice] child pid 22845 exit signal Segmentation fault (11)

I have generated a backtrace (sorry, apache is not compiled with debug information - only PHP):

Starting program: /usr/local/apache/bin/httpd -f /usr/local/apache/conf/httpd.conf -X

What was the configure line used for PHP 4 ?

--Jani

[2001-03-09 18:50 UTC] michael at carceri dot dk

Sorry, I forgot the configure line. It's:

--enable-track-vars --with-mysql=/usr/local/mysql --with-mhash --with-mcrypt --with-apxs=/usr/local/apache/bin/apxs

[2001-03-10 19:58 UTC] sniper@php.net

What is the mysql version you are using?
And have you tried the latest CVS snapshot from http://snaps.php.net/ as I can't reproduce this with
latest CVS.

--Jani

[2001-03-10 19:59 UTC] sniper@php.net

ehm..sorry, I just noticed that you had tried with
latest CVS. Or have you? Could you please try and update
your checkout?

--Jani

[2001-03-10 21:08 UTC] michael at carceri dot dk

I have tried with the CVS snapshot from 09/03/2001, but can try with a newer snapshot if you need it.

I use MySQL version 3.22

Please add a shortest possible script into this bug report, which can be used to reproduce this.

--Jani

[2001-03-16 21:00 UTC] michael at carceri dot dk

Sorry, this problem is not MySQL related after all. It's caused by calls to mcrypt functions used in my database php file. I have created a new bug report under "mcrypt related". Please close this one.

Closed per user request.
