There is a similar bug that is tickled when your armor is rusted.
This only happens on machines with unsigned ints (such as the IBM RT).
There is an implicit assuption in many places in ularn that negative
numbers can be stored in chars, without explicitly declaring the variable
to be signed char.  This can be fixed by changing by changing the
declaration.  I've only bothered to change this for rust monster bug
mentioned above (change rustarm to be an array of signed chars in 
monster.c).  I know that a similar change needs to be done in the 
code to display inventory of dead characters (the -i option), and
I'm sure it occurs in other places as well.

I'm not sure if this is your problem, however the above fixes should be 
made.
