Also present in 2.5.1. There is no output, but I confirmed manually that this is caused by SIGBUS. Backtrace and UBSAN run forthcoming. Reproducible: Always

Created attachment 880970 [details] UBSAN run So, the first failure is actually a fault in media-libs/sdl2-ttf. However there is a second failure that I suspect will come up next should the first one be fixed. loading pygame.tests.font_test /var/tmp/portage/media-libs/sdl2-ttf-2.20.2/work/SDL2_ttf-2.20.2/SDL_ttf.c:919:9: runtime error: load of misaligned address 0x0001478311c7 for type 'const Uint64', which requires 8 byte alignment 0x0001478311c7: note: pointer points here 00 00 00 00 01 01 01 01 01 01 01 01 01 01 00 00 00 00 00 00 00 01 01 01 01 01 01 01 01 01 01 00 ^ Culprit somewhere in here: https://github.com/libsdl-org/SDL_ttf/blob/release-2.20.2/SDL_ttf.c#L910-L926

How much do we really care about this? The only sparc keyworded package with a dependency on sdl2-ttf is pygame. Meanwhile, the only sparc keyworded package with a dependency on pygame is dev-python/pyopengl. There are no sparc keyworded revdeps of that. If no one answers soon, I will drop the keywords on all of them.

Whenever I file these bugs that's always a perfectly valid solution. Especially on ppc which has a ton of junk with no business being keyworded there.
