The bug would occur in round-to-nearest mode when the result, rounded to twice machine precision, was exactly halfway between two machine-precision values. The essence of the fix is to simulate a "sticky bit" in the pathological cases, which is how hardware implementations break the ties. MFC after: 1 month END
