I am running the php CGI in shell scripts.  

A database SELECT downloads a list of websites (that are known to exist)  and feeds each IP address like so:


$meta_data = get_meta_tags(http://$url);

And it frequently segfaults - often when it reaches the same site.  Could it be a problem with the URL?  Here is the backtrace on the core from gdb:

Core was generated by `php -q ./test.sh'.
Program terminated with signal 11, Segmentation fault.

PHP was compiled with the following 'configure' flags:

./configure --with-mysql --with-gd --with-snmp --enable-debug --enable-track-vars

Thanks in advance !!
