--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. The change was desired and the outcome is desired as well. The
warning code needs to deal with this. We only optimize this after the
strlen pass which runs pretty late and transforms the two calls to memcpy_chk
calls (w/o folding them it seems so it takes until VRP/forwprop to finally
fold them).
There's a missed optimization opportunity in merging the two aggregate copies.
