I am not sure why honestly reporting the absence of this extension would cause your game to crash. However, if the game is not too taxing, you might be able to work around this problem with `LIBGL_ALWAYS_SOFTWARE=1 wine my-game.exe`.
The game crashes in the same way with the software renderer too.

I would guess this is similar to bug 38480. Does the following patch help?

Technically its a bug in Mesa, but imho we could easily fix it / workaround it on our side.
The patch indeed makes the crash go away.
