Description Martin Gerhardy 2011-11-20 09:29:10 UTC 
I'm not sure whether it's a problem in SDL_image or SDL. But loading an image with SDL_image 1.2.10 on an intel mac 64 bit results in a segfault (bt full is attached)

The SDL version that was used was SDL 1.3 from Nov. 15th

------------------snip----------------------------------

	SDL_Surface *surf = IMG_Load(file.getName());

	SDL_PixelFormat format;
	memset(&format, 0, sizeof(format));
	format.BitsPerPixel = 32;
	format.BytesPerPixel = 4;
#if SDL_BYTEORDER == SDL_BIG_ENDIAN
	format.Rmask = 0xff000000;
	format.Gmask = 0x00ff0000;
	format.Bmask = 0x0000ff00;
	format.Amask = 0x000000ff;
#else
	format.Rmask = 0x000000ff;
	format.Gmask = 0x0000ff00;
	format.Bmask = 0x00ff0000;
	format.Amask = 0xff000000;
#endif
	format.Rshift = 24;
	format.Gshift = 16;
	format.Bshift = 8;
	format.Ashift = 0;

	// here comes the segfault
	SDL_Surface * converted = SDL_ConvertSurface(surf, &format, 0);

this can be closed - it works with the latest sdl version.
