--- Comment #15 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
Is this something which could also have caused wrong-code issues in
other circumstances, which we just didn't happen to find until
this was exposed by Andre's patch and the test case?

In other words, should we backport Mikael's patch?
