This looks like a real API failing in the wrapper.  Basically I didn't
realize that passing in a NULL with a real size was valid when I did
that wrapper, now even if I didn't I likely wouldn't have wrapped it
quite that way (i.e. I would have made a wrapper that allowed passing
size or not, instead of always taking size from the array).  Will have
to rework the function's wrapper to allow passing in size explicitly.

Thanks for pointing out the problem,
Mike
