Summary: Very big integer arithmetic crashes GHCi on Windows and Mac

Initial Comment:
With GHC 6.4, interpreted or compiled, on Windows and 
Mac OS X, 
evaluating the expression (4^(4^44))::Integer causes a 
crash.

On Unix, it just goes out to lunch and eats memory, 
which seems more plausible.


On Mac, the message is:
