--- Comment #26 from Vitaliy Margolen vitaliy@kievinfo.com 2009-10-20 23:01:14 --- I have the same problem here. Getting a useful backtrace is some-what challanging. This is a ddraw app that keeps getting DIB section access segfault on each element drawn. And when the crash happens the whole thread is gone with it's stack... On top of that crash happens after 1..10 minutes of game-play.
And I do confirm that reverting 6b875318 patch on current git does fix the problem.
