Do you have 64-bit Linux and experience frequent crashes? It’s known OpenAL problem.
- Report about that problem to your distro’s bug tracker.
- OpenAL must be built without MMX support. There’s no performance penalty on modern platforms. Also you could remove
__MMX__related code by yourself, as I did for debian packages. - As a temporary solution — you could switch off sound with
command line argument or set--no-sound disable-music /sound in ~/.btanks/bt.xml.
