From: michael@carceri.dk Operating system: Linux 2.4.1 PHP version: 4.0 Latest CVS (09/03/2001) PHP Bug Type: Reproduceable crash 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 (no debugging symbols found)...(no debugging symbols found)...
