--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Well this code is undefined anyways.
Plus we don't find out that we don't need the chain until it is too late (RTL
expand time).

I am going to close this as invalid as &x-&a and &y-&a is undefined and does
not mean the location will be fixed for the whole time as only a should be
considered as being escaping.
