This has nothing to do with QC version. Just usual floating point shenanigans. Single precision float is not difficult to overflow with maximum finite number of about 1e38. In this example multiplication first overflows to infinity and then is multiplied by zero (second to last) getting NaN.
I guess we should use newtype wrapper over floats for which NaN==NaN = True

QuickCheck-2.14.3
changed instance Arbitrary Float
to generate more "interesting" numbers, thus increasing chances of this fault to almost 100%.
