[Freeciv-Dev] (PR#6337) Hash registration

["Cameron Morland" <cameron@xxxxxxxxxx>]

Hi,

I don't know what to do in this circumstance. In sanitycheck.c:279 we
want to assert(!is_ground_unit(find_unit_by_id(punit->transported_by))),
but find_unit_by_id returns NULL in my particular case, indicating that
the unit is not "registered". I don't get this hash stuff; what should
we do if the unit is not registered?

Unfortunately I seem unable to cause this particular crash to occur
again, but if someone could answer, I'll know next time.
