--- Comment #14 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Can we close this?

(N.B. https://gcc.gnu.org/ml/libstdc++/2015-02/msg00040.html will make further
changes to these functions to fix PR65033, but only to make them account for
mis-aligned types, they will still be per-type not per-object)
