The cause of the problem is probably in this: if you try to inspect
dzindzik, VM prints out something like "Directory does not have index:
7". If you try dzindzik instVarAt:1, dzindzik instVarAt:2, ... in a row,
you get 6, but there is not 7.
So dzindzik's class thinks it has (at least) seven inst vars, but in
fact in does only have six.
