Looks like a bug/inconsistency in H98 to me:
    The prefix "generic" indicates an overloaded function that is a
    generalised version of a Prelude function.
so I'd certainly expect the generic versions to behave the same if used
at type ...Int...

Malcolm, do you agree? Can this go in the H98 errata?
