Just to be pedantic, the standard doesn't guarantee that the expression
you use will test what you want to test. Since there is a guarantee that
malloc() returns a universally aligned memory, I think it's actually
more likely that the test will fail than that malloc() will fail, though
both probabilities are quite negligible, so it's hard to be sure.
