IMHO this is hard to tell what is the problem without seeing source code...
if Your's program is simple maybe You can post it source code ? I have now
meany free time, so You can email source to me if You wish. I think that
this is some tipical memory error (like reading illegal index from array, or
deleteting/freeing invalid pointers) - and often frequency of hangups with
this bugs depends on platform (DOSBox or Dos etc....)
