Ack, that works fine. I honestly didn't think that anyone would have
tried a -O0 compilation. I'm a bit surprised it depends on optimization
levels, though -- maybe the result has *too many* types and the
comparisons fail as a result?

Still, -O2 is a valid fix and doesn't stop the test checking what it's
supposed to, so go for it.
