There is an optimization rule that removes calls to racefuncenter and racefuncexit, if there are no other race calls in the function. The rule removes the call to racefuncenter, but it does *not* remove the store of its argument to the outargs section of the frame. If the outargs section is now size 0 (because the calls to racefuncenter/exit were the only calls), then that argument store clobbers the frame pointer instead. The fix is to remove the argument store when removing the call to racefuncenter. (Racefuncexit doesn't have an argument.)
