the "cmap->clazz" value is definitely wrong, and there is no way the 
charmap was built
with it. In other words, the field has been rewritten after creation of 
the charmap !!

Can you re-run the program but set a watch on the fields's memory 
address ? This would
help us spot the problem.

Thanks in advance,
