bastien.bouclet When creating two surfaces and blitting them onto the other, SDL's internal reference counting fails, and one of the surfaces is not freed when calling SDL_FreeSurface. Example code : SDL_Surface *s1 = SDL_CreateRGBSurfaceWithFormat(0, 640, 480, 32, SDL_PIXELFORMAT_ARGB8888); SDL_Surface *s2 = SDL_CreateRGBSurfaceWithFormat(0, 640, 480, 32, SDL_PIXELFORMAT_ARGB8888); SDL_BlitSurface(s1, NULL, s2, NULL); SDL_BlitSurface(s2, NULL, s1, NULL); SDL_FreeSurface(s2); SDL_FreeSurface(s1); With this example, s1 is not freed after calling SDL_FreeSurface, its refcount attribute is still positive.
