It's possible, but I am not entirely familiar with the initWithFrame function, that the OpenGL context does not exist at the point that you set up the pointers. Try moving your *Pointer calls to somewhere later in the program where you know you are within the OpenGL context (or right before the draw calls just as an experiment).
