I think that's a fair question, and it's about safety. If you're getting
this on the JIT, means we may be generating unsafe transformations on the
vectorizer.

Arnold, Nadav, I don't remember seeing code to generate any run-time
alignment checks on the incoming pointer, is there such a thing? If not,
shouldn't we add one?

cheers,
