Yeah, not much of a surprise since the pointer might still be valid or
at least readable (even if the data there is garbage) ... if we get a

But we try to run with many debug options turned on anyway, so I don't
know why this showed up only recently. Maybe some unrelated changes
(compiler changing to load the pointer again, for example)
