Public bug reported: This bases on this minetest (http://minetest.net) valgrind-log: http://pastebin.com/Dm9S6Cu7
Reproducability: 1. Install some Minetest version from 0.4.0 through 0.4.11 (other versions perhaps too) 2. Start a new game and enable sound. Minimal development test executed locally is enough. 3. Do something in the game that causes a sound. 4. the game crashes. >From the valgrind stacktrace you can see the error was caused by the call of the "MixDirect_SSE" function. After googling that name, I've found somebodies forum post that suggested to compile libopenal without support for SSE (http://www.soldak.com/forums/showthread.php?p=72247). After I've passed "-DSSE=OFF" to the cmake, the crash wasn't reproducable anymore. Apparently the SSE support for openal is buggy. Could you inform upstream of the issue and turn it off until there is a fix? The output of the gdb bt command is changing from crash to crash, therefore use valgrind to get the stacktrace. To enable actual speeds, its best to turn all graphical features off. Note that the stacktrace linked above wasn't created with the official utopic ubuntu library version, but by a build of the openal- soft_1.15.1.orig.tar.bz2 with debug symbols enabled to help fixing the bug.
