I've forgot a cast, '(ULONG) __builtin_return_address(0)' should work.

I hoped to see the dump from the memory statistic before or within this
lines. Can you add a bug check after line, 1626? This crashs ros and the
stack dump shows the caller of the allocation. Im not sure how much
memory colinux needs. If you start a clean windows with and without
colinux, you can compare the using of the non paged pool. The task
manager shows this value on the performance page as kernel  memory.
