 be fixed in 8.0-RC2:

I remember looking at this bug and tried to reproduce it ...

If my memory serves me right, I believe this bug was fixed by
svn r197364, committed on 9/20.  RC1 was built on 9/17.

Another symptom of this bug is the "route get" command issued
on any lo0 addresses returns "destination: default" instead
of "destination: lo0".

That indeed looks like the culprit, thanks for fixing it.
