--- Comment #16 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I should mention in my reduced testcase if I change the name of either function named z to something different, we get the correct result which is why I mentioned: "the front-end seems to have copied the body of the first one into the second".
