THis is an easy HO to have, and that is why I noted
the example, but look more carefully at my example,
it is not comparing empty arrays, it is comparing
deferenced null pointers, and a constraint error
is required even though there is nothing to compare!

Actually, in this simple form, a compiler is not
likely to get this wrong, since there are simple
examples like this in the ACATS test suite.
