Bug description:  PHP sometimes dumps core

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
