The logic in the isValidSegment() function was failing for 8-bit signed
because for them Integer(SegmentUnknown) is -1, so
(std::numeric_limits<Integer>::max)() < Integer(SegmentUnknown)
was always false (127 < -1) and the function would only return true on
the impossible condition of
segment >= 0 && segment < -1
