Here is a funny program that gives wrong result because of length
returning Int on a 32-bit computer.

    import Data.List
    main = print (length (genericTake 5000000000 (repeat ())))

Running it shows

    $ ./A
    705032704

But this is a strange piece of code and I agree that it will hardly be a
problem on a 32 bit platform.

I believe it's impossible to write similarly behaving program for
Data.FiniteMap with current compilers and libraries.

Best regards,
Tom
