Public bug reported: After the upload of libsdl2-2.0-0 2.0.6+dfsg1-2ubuntu1, it looks like some programs (like Widelands) crash when they try to play sounds.
Based on the SDL2 upstream discussion (https://discourse.libsdl.org/t/sdl-2-0-6-released/23109) it seems to be a bug with the new version if libsdl2 and libsdl2-mixer. Steps to reproduce: (Install Widelands as an example which uses sdl2 and sdl2-mixer) 1. Run widelands 2. From the main menu, select Single player 3. Select New game 4. Pick any map and click Ok. 5. Click start game. Expected The game starts Actual It crashes, with a segmentation fault. (See bug 1720819 for example output and backtrace) This was originally reported upstream in Widelands and tracked down to a bug in sdl2 version 2.0.6, see bug 1720819 for more details. In particular the following comments: https://bugs.launchpad.net/widelands/+bug/1720819/comments/14 https://bugs.launchpad.net/widelands/+bug/1720819/comments/16 (which contains a possible patch for SDL-mixer) Known workarounds As mentioned in the commenst https://discourse.libsdl.org/t/sdl-2-0-6-released/23109, it seems to be related to the sound and sdl_mixer. In the case of Widelands, it is possible to run `widelands --nosound` which will mute all sound. With this option, the crash doesn't occur. Possibly other programs are affected by this as well.
