--- Comment #1 from Vincent Povirk madewokherd@gmail.com 2010-10-13 17:04:20 CDT --- Created an attachment (id=31259) --> (http://bugs.winehq.org/attachment.cgi?id=31259) work-around patch
The problem is that IDirectMusicPerformance8Impl_AssignPChannelBlock gets a high dwBlockNum and accesses a value that's out of range. The attached patch works around it but is the wrong approach.
