This is an interesting pickle.
We actually have a *ton* more of these kinds of tests, but the
customer in question hasn't yet officially allowed us to contribute
them, even though we know they're going to at some point. Lawyers.
It turns out to be very hard to write such tests in a portable manner.
The layout algorithms vary enough from machine to machine that even
though the C++-specific bits stay the same (where do you put the vptr?
which base gets laid out first?) you find everything else moves around
a lot.
