--- Comment #3 from Tobias Burnus <burnus at gcc dot gnu.org> --- Our nightly tests have: PASS on 2020-01-29 FAIL on 2020-01-30, 2020-01-31 PASS on 2020-02-01, 2020-02-02 (I couldn't find older data.) — Hence, it looks also like intermittent failures. Still, I think/hope Jakub's fix for PR 92305 is the only needed patch. Can you re-check whether you are still getting this?
