Ok for mainline?
Forgot to ask: Ok for backporting to all open release branches? The fix
is in trunk for two weeks, now, and it was reproducible for me until gcc
8 (probably even earlier but I stopped at 8). Furthermore, the fix
seems innocent in the sense that its effects are local.
Yes. I can backport the patch if you want. It is safe.
