No kernel oops?

In a device driver that I am writing I have something like:

int zr_read (struct virgo_s *board, int reg)
return ((int *)board->base)[reg/4];

As an unfortunate accident, I was calling this with "board == NULL".
I had expected to see an kernel OOPS. when this happened. None
of this: it simply returned a memory location.

The virgo_s has "base" as its first element.

Anybody know why I didn't see an oops?
