Fixed crash:

#include <SDL.h>

int main(int argc, char** argv)
{
        SDL_Init(SDL_INIT_EVERYTHING);
        SDL_SetVideoMode(640, 480, 0, SDL_FULLSCREEN);
        SDL_ShowCursor(SDL_DISABLE);
        SDL_Delay(1000);
        SDL_SetVideoMode(640, 480, 0, SDL_FULLSCREEN | SDL_OPENGL);
        SDL_Quit();
        printf("Everything okay\n");
}
