--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
So if it's possible to refactor things as to key the copy size dispatching =

the destination size (that seems to be known here) rather than the source
that might help (unless we then diagnose overread from the source in other
cases ...)=
