Package: gltron Version: 0.70final-12.4 Severity: normal Tags: upstream To reproduce:
* run gltron * use your desktop environment or window manager's keyboard shortcut for closing the window, normally Alt+F4 Expected result: the game quits gracefully. Actual result (with libsdl1.2debian): the game crashes with a segmentation fault. Actual result (with libsdl1.2-compat-shim, or with libsdl1.2-compat 1.2.58-1 added to the LD_LIBRARY_PATH): the game hangs indefinitely, becomes unresponsive to SIGINT and SIGTERM, and must be killed with SIGKILL or similar. I reported this to sdl12-compat upstream while testing various Debian games' compatibility with sdl12-compat, and sdl12-compat maintainer Ryan C. Gordon diagnosed the problem as follows: > This happens in glTron because it gets the SDL_QUIT event [...] > which calls [SDL_Quit()] but never sets return_code to exit the loop. It > should probably just do that and not call SystemExit, as I assume leaving > this loop will do that too without risking another call into SDL. > > In real 1.2, it eventually calls SDL_GL_SwapBuffers after that SDL_Quit > and dereferences a NULL pointer; in sdl12-compat, we just keep ending > up back in current->idle() calling SDL_Delay() without crashing.
