That's what I would expect to happen if you don't use -W in psql.
What I suspect is happening with the MS KDC is that an additional
call to the conv_proc happens later with some parameter values that
we aren't prepared for. Can you stick some debugging printout
into the checks at the very top of the routine?

I think you need to add some braces if you don't want to break the
behavior here. This is C not Python ...
