I’m calling SDL_UIKitRunApp to start my iPhone program due to some linker errors (I’m using Pascal) and everything works fine (SDL_Init is called without error after entering SDL_main) but when I call SDL_CreateWindow I get this crash deep in the call stack.
I know I don’t have much info for you but that’s the nature of using non-C languages with SDL and all the particularities of the compilers build system.
Do you happen to have any idea what could possibly be causing this? Any tips would be great.

If for any reason at all it helps to see the Pascal program.
