ID: 7802 Updated by: stas Reported By: erik.monson@gte.net Status: Closed Bug Type: *URL Functions Assigned To: Comments: OK, crash should be fixed. Please verify and repoen if it still happens. Previous Comments: --------------------------------------------------------------------------- [2000-11-15 04:18:00] stas@php.net Verified - crashes on http://151.196.200.20 (warning: this is an adult site, so I am not responcible if you get a heart attack after looking on it, I need it only for HTML parsing debugging :) --------------------------------------------------------------------------- [2000-11-14 06:12:51] stas@php.net Can you please give one example of URL where this function crashes? --------------------------------------------------------------------------- [2000-11-14 04:54:26] erik.monson@gte.net 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.
