--- Comment #2 from mikos@esc.net.au 2008-04-12 04:00:29 --- I checked with wine 0.9.57.
Sorry, it was alsa that was at fault here. I can reproduce the crash by playing any sound in BabasChess many enough times.
Still I don't think I can rule out a richedit problem just yet because I tried this before I played around with the sound settings and found wine 0.9.47 to be stable and 0.9.48 not to be.
Hopefully I can get wine to crash with OSS sound instead of ALSA and attach the output.
