Can we please make this P1 rather than P2? It is a wrong-code
regression and only present in a single release, so by the bug
management guidelines (https://gcc.gnu.org/bugs/management.html) I
think it should be P1.

There is already a working patch, test-case, and discussion on the
gcc-patches list so I don't see what's blocking fixing it before the
next release.
