The patch below fixes it, but I am not 100% happy with it. Calling
resolve_ref means we actually bother to look up the ref again, which is
wasted effort. The ref struct has a "symref" field which should contain
this information, but for some reason it is not recorded. So we can
probably do better by simply recording the information properly when we
resolve the ref in the first place.
Unfortunately, I don't have time to look at it anymore right now, so it
will have to wait.
