I took the liberty of backporting because the release of 8.3
will be rather soon (if it occurs on time), and I wanted this
patch in.  Tobias, I hope you don't mind.

Therefore fixed on all open branches, closing.

--- Comment #9 from janus at gcc dot gnu.org ---
Tobias, are you going to backport the fix to the release branches?

Jakub's comment 8 sounds like it might already be too late for 6.5, but it
would be great to have this at least on the 7 and 8 branches!
