--- Comment #16 from Pavel Ondračka pavel.ondracka@email.cz 2011-02-11 12:57:52 PST --- I've found my copy of C&C3 so I thought I'll try to reproduce this. However I don't get any crash at startup. I get a crash when switching desktops or alt-tabing from game, but backtrace doesn't show any signs of a driver crash, so this is probably some unrelated Wine or C&C3 crash.
Martin, here is what I found when looking into this that you may find useful. IMHO you aren't getting backtrace because the crash is happening in some other process. You need to start the game, switch to terminal, start winedbg, list process, attach to the right one (probably cnc3game.dat or some other) and trigger the crash. Hopefully you will get some backtrace then.
