I'm not sure how to get the standard library version that is being used, but our internal upstream build bot hit this issue, and it is running ubuntu 18.04 with gcc 7.5 as well.

My main dev machine is running ubuntu 20.04 with 9.3 and that does not show the failure, but another one of our internal linux machines with 18.04 and gcc 7.5 does show the failure.
