Believe it or not, this is actually safe.

What do you mean by "is actually safe" ? In the "can you actually
believe this obviously wrong code is marked as safe" or "this
code that looks wrong is actually perfectly safe"?
AFAIK, it's only safe if arr is GC allocated to a bloc smaller
than a page, so the conditions are implementation defined
behavior, and so is the result.
