rc1 and rc2-dev SIG11 problem

Compiled as a CGI module and running a script from the cron on a FreeBSD 3 machine I often get this coredump: GDB is free software and you are welcome to distribute copies of it under certain conditions; type "show copying" to see the conditions.

It is the always the same script, which reads content from a website using fopen("http://") parses html and puts the results in a mysql table. There might be a bug in the script, but it's not supposed to sig11 php right? Running the script manually from the shell never caused a coredump, I tried many times... Any hints on how I can debug this further is appreciated... Thanks Paul
