Cannot recover after last error

Hi all,

Validating this URL on Validator.nu makes it crash with a "Fatal Error:
Cannot recover after last error. Any further errors will be ignored."

http://validator.nu/?doc=http%3A%2F%2Fvalidationhell.com%2Fpages%2Fabyss%2F99

Please notice that this site is intentionally invalid, it's the one I use
to test validators, but I thought you'd like to be notified of this issue.

Regards,
