Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP --
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php
If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
and we now bundle our own GD for your chewing enjoyment!
