http://bugs.winehq.org/show_bug.cgi?id=58313 --- Comment #3 from Alex Henrie <alexhenrie24@gmail.com> --- Created attachment 82098 --> http://bugs.winehq.org/attachment.cgi?id=82098 Mutex in FileLockBytesImpl_ReadAt Interestingly, making FileLockBytesImpl_ReadAt thread-safe appears to completely fix the crashes. The MSDN documentation for ILockBytes::ReadAt [1] does not claim thread safety, but I wonder if Windows implements it in a way that happens to be thread-safe anyway.
