PHP 4.0 Bug #7802: get_meta_tags() segfaults on certain sites

From: erik.monson@gte.net Operating system: Linux 2.2.X SMP (Mandrake 7) PHP version: 4.0.3pl1 PHP Bug Type: *URL Functions Bug description: get_meta_tags() segfaults on certain sites 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.
