Comment(by ross):

 Replying to [comment:20 daniel.is.fischer]:
 > I thought so, too, for a while, but when I tried that, I ran into gcd
 minBound (-1), which throws the overflowError
 because rem minBound (-1)::Int throws overflowError, but surely that's a
 bug: quot minBound (-1)::Int should overflow, but rem minBound (-1)::Int
 should be 0.
