--- Comment #8 from Reece Dunn msclrhd@gmail.com 2008-12-03 03:45:47 --- When I tested it with wine-1.1.8, it failed on the first go, so it can't be your patches.
Trying with wine-1.1.5, it failed once in 15 tries. I'll need to retest wine-1.1.8 to see how often it fails. I don't fully understand this yet, so I don't really trust the bisect results here.
