Mike Crowe <mac at mcrowe dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mac at mcrowe dot com --- Comment #7 from Mike Crowe <mac at mcrowe dot com> --- I think that https://gcc.gnu.org/ml/gcc-patches/2019-10/msg01934.html fixes this for std::future::wait_for but without the __chrono_detail part mentioned in comment 5. std::shared_timed_mutex was fixed in r278903/ab40695a46c6649bac40f4251e37993d73fa7a13.
