Does it still happen for you? Is it deterministically reproducible?

I am afraid sys-devel/gcc-7.2.0 is no longer in portage now, but yes it was deterministically reproducible

[Comment 6 Sergei Trofimovich (RETIRED) 2020-02-02 00:06:18 UTC]

Let's declare it obsolete then. Please file a new bug if it happens on newer version.
