Bug Description

Binary package hint: php5

See the atteched PHP script for an example that will crash PHP.

This could be (is likely to be?) a bug in libxml2, but I'm not one to make that call.

Thanks taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the bug has been fixed in the latest development version of Ubuntu - the Gutsy Gibbon.

If you need a fix for the bug in previous versions of Ubuntu, please follow the instructions for "How to request new packages" at https://help.ubuntu.com/community/UbuntuBackports#request-new-packages .

No, I don't; just wanted to make sure the bug was known, but it's not
really hassling me anymore. :) Thanks, though.
