I reported it upstream but it hasn't shown up on the bug tracker yet. The fix isn't so trivial.

[Comment 9 Michael Orlitzky 2020-01-30 14:16:25 UTC]

This is fixed upstream already and will be a part of the next release. So long as that happens before gcc-10 comes to gentoo, I don't see a pressing need to backport the patch.
