The description provided (and the register dumps) lead me to believe you
are getting exceptions inside exceptions, which means the exception 
area itself is corrupted.  I would guess it's a stack sizing problem.
Try to stubedit in a 4Mb stack (or more if you see a lot of big automatic
arrays in the source).

Humm, maybe it's time to break out the stack usage tools for general
consumption (sigh).
