Please attach your xorg log and dmesg output.  Also is this a 32-bit game running on a 64-bit distro?  What do you mean by crash?  segfault?  system hangs?  If it's a segfault or something like that can you get a backtrace with gdb?

Xorg.0.log

Yeah, it's segfaulting. It is 32-bit running on 64-bit Ubuntu, but I do have multiarch support (and TF2 works fine, which is nearly the same engine and also 32-bit).

If I am debugging it with gdb, it won't go past the loading screen for the main menu. The last thing gdb says is "0xf776e425 in __kernel_vsyscall ()
". I don't know what that means.

Is the libgl1-mesa-dri:i386 package installed on your system?

That's too little information. If you don't know which output from gdb is relevant, please just attach all of it.

That package is installed. I should have been more clearer, that was the only thing it outputted besides it informing me that it's loading debugging symbols. 

Oops.... I made a mistake when using gdb. I'll post the corrected information shortly.

I can reproduce this bug on rv770.
It works fine on mesa 9.0.3 and 9.1.1

I've bisected to this commit:

    st/mesa: accelerate glGetTexImage for all formats using a blit
    
    This commit allows using glGetTexImage during rendering and still
    maintain interactive framerates.
    
    This improves performance of WarCraft 3 under Wine. The framerate is improved
    from 25 fps to 39 fps in the main menu, and from 0.5 fps to 32 fps in the game.
    
    v2: fix choosing the format for decompression

gdb output

The interesting stuff is near the bottom. It segfaults on st_GetTexImage in st_cb_texture.c on line 895, which makes considering Andreas' post about Warcraft III in Wine.

*makes sense, I meant to say makes sense.

It's interesting that it's segfaulting in different places for each of us.

Could you please try this patch?

possible fix

Which package is this? Is it libgl1-mesa-dri?

It's a git patch for Mesa, applicable using "git am -3". Of course it's the DRI driver.

Since I'm using xorg-edgers, do I need to check out from git or can I just use apt-get source?

Sorry I don't really know what needs to be done if you have xorg-edgers. The patch is supposed to be applied using the git command, so you basically need the whole Mesa git repository.

I checked out from git and applied the patch, BUT autogen.sh exits with code 1, configure has a syntax error, and make says there is nothing to do.

Please attach the output from autogen.sh / configure. There's no point running make until those have succeeded.

Thanks Marek, your patch fixes the segfault.
Feel free to add my Tested-by on the patch.

It fixes this issue for me too, thanks.

The patch works for me.

Marek, your the latest commits in master mesa git repo don't solve this problem.
