--- Comment #6 from joaopa jeremielapuree@yahoo.fr 2008-06-05 02:49:44 --- I already explained what is happened with amstream now.
Before my patch, some applications crashed because of the lack of checking the condition in my patch. But other applications took care of it, and skipped the amstream stuff gracefully. So the applications did not crash. Now with my patch, the applications go on further but crash in amstream because some methods are not implemented even not stubbed. This is proved by reading the debug trace with this patch and by reverting it.
So, I think that for wine 1.0, it would be better to revert this patch, then implement all the missing methods (even stubs would be good) then reapply the patch.
