Hi, I discovered that games-arcade/supertux-0.1.3 segfaults with the --sdl backend on x86. Unfortunately, the sdl backend seems to be the default backend when no configuration is found, even if it was built with USE="opengl". I can reproduce the crash on two differents x86 systems. Reproducible: Always Steps to Reproduce: 1. install games-arcade/supertux-0.1.3 with USE="opengl" on x86 2. run : supertux --sdl Actual Results: crash with segfault Portage 2.1.9.25

Try it with the latest version of libsdl and see if that makes any difference.
Yes, does not crash with libsdl-1.2.14-r4, thanks.
I can also generate a segfault and a hard machine lock with r128 and ATI M4 32MB. Dell Inspiron 8000 If sdl is built with 'aalib' in USE flags. setting via export the SDL_DISPLAY to x11 fixed that. Or remove the support for aalib (ansi art) from sdl
closing now that the newer libsdl is marked stable.
