FYI: SDL_GetError() returns 'char*', not string. you can print error
message with this code, for example:

  private void sdl_print_error () @trusted nothrow @nogc {
    import core.stdc.stdio : stderr, fprintf;
    auto sdl_error = SDL_GetError();
    fprintf(stderr, "SDL ERROR: %s\n", sdl_error);
  }

besides, i don't think that you'll get something sane from
`SDL_GetError()` in the case of segfault.
