That may have been a case where the FMA instructions on Xbox 360 gave different results. Or maybe the code was relying on the x86's odd x87 floating-point unit, or maybe the compilers were rearranging the instructions slightly in one of the ways that is legal. Lots of reasons why floating-point math code might behave differently without it being a CPU or compiler bug.
