--- Comment #6 from Gilles Gouaillardet <gilles.gouaillardet at gmail dot com> --- I am happy to confirm this issue is fixed in the latest 12-20210919 snapshot :-) FWIW, I was not yet able to build GROMACS because of an other issue that was introduced last week. I reported it at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102421
