It's not random, but clearly reproducable, see below.

The crashes occur without audio, too.

--enable-coreaudio
is automatically added when using --enable-cocoa. I added it just for  
SDL builds, since SDL audio is not really usable on OS X...

Yes, the Problem with gcc 4is user-mode.

You find a freedos including doom here:
http://www.kberg.ch/q/userfiles/freedosdoom.zip

or at the oszoo.org

Crashes:
- when choosing option 1 (standard)
about 10-20 sec into doom, when playing timedemo (doom -timedemo  
demo3), otherwise, too.


This used to work great before.

Thanks,
