OK. Good. So I'm not losing my mind. This is a fairly recent change
and just exposing a latent bug (I still consider the old code buggy, if
it wants to copy rtxs, then that's what it should copy, not rtunions).

Agreed. And that's what I did locally so that I could actually get some work
done on this port while we researched the problem.
