David Carre to Sam When i call the "SDL_Quit()" function, it call the func "SDL_QuitSubSystem(SDL_INIT_EVERYTHING)", which call the "SDL_VideoQuit()" function. It's where i'm lost, this function "SDL_VideoQuit()" will recall the "SDL_Quit()" function (i don't find where it is called), which in turn recall the "SDL_QuitSubSystem(SDL_INIT_EVERYTHING)", which in turn recall "SDL_VideoQuit()", which cause a "double free" seg fault since it has been already called. I have set the num_displays to 0 instead of 1, so it wont free it twice in the videoquit function loop.
