Yeah, but none of the modified code would even execute in those cases,
so it's either binary layout, something wrong in your test
environment, or gremlins.
I'm not going to the office all that often these days, but I think I'm
sure I'd notice a bunch of gremlins running around ... so it's probably
the binary layout thing. But still, strange.
