I'm interested in that as well.

Opera is working on it. Though as pointed out earlier I would like to 
have some
more clarifications on how exactly comments are supposed to be handled.

Per the specification it would be an empty bogus comment.

don't have this crash and do the same as Opera 8.5. As in, not exposing it in
