I'd say it's up to the port maintainers to decide if/how they want to
handle this case.  Basically I'm less concerned about fixing warnings
in the backends right now than finishing some of the other stuff
on our collective plate.

An abort is probably the best thing to do since (in theory) the
output code handles all the cases that can actually occur.
