Fixed bug #570 SDL_SemWaitTimeout in src/thread/generic/SDL_syssem.c line 179 (SVN trunk): --sem->count; should be if (retval == 0) { --sem->count; } Without this, sem->count will underflow on timeout effectively breaking the semaphore. It appears that the implementation has been wrong since the initial revision.
