Here is a diff for unbreaking games/supertux, which segfaults on startup. I opened an issue explaining the bug here: https://github.com/SuperTux/supertux/issues/1726
I bisected and found a commit from 2.0.10 that caused this segfault: https://github.com/libsdl-org/SDL/commit/670f3d3327912b299e8e5ea9de4f01bd833414cc It reads out of bounds memory due to usage of SIMD functions since SDL 2.0.10. My workaround is to make the resolution larger for the affected image. I get the same backtrace on startup. Tests and feedback are welcome. OK? I would like to get this in to unbreak games/supertux, but it is almost ports lock.
