So the error isn't really divide by zero, but overflow.  I've been
bitten by this, too, and L.Guo should count him/herself lucky to get an
error, and not just incorrect results.

IMO, this is a rather nasty hole in the safety nets that Haskell is so
abundantly endowed with.  Does any Haskell implementation support
overflow detection?
