From the backtrace I don't see how this could happen without memory
corruption.  In the call to real_map_distance tile0 and tile1 are equal,
however in the call to map_distance_vector tile1 is changed to "2".

I'd like to see the results of this autogame under valgrind but my
computer would take forever to get to year 2020.  If someone can run
this and see what you get (you probably want to see if you can reproduce
the original bug first) I'd like to see the output.

This is not the same as the other reported bug in this ticket.  We
should try to separate these into different tickets in the future.
