phew!

Well...as long as you don't shoot yourself in the foot :-)

I think your train of argument is (formally) correct.
I agree with Doug Gwyn however that allowing the calloc to fail to ensure
that a _possible_ sizeof call will succeed seems to be putting the cart
before the horse. It makes more sense to me to just define nonconformant
behaviour for sizeof for objects larger than size_t can handle.

Of course :-)
