--- Comment #4 from Florian Weimer <fw at gcc dot gnu.org> ---
I think it's a test bug:
std::atomic_ref<S> a{ aa };
std::thread t([&]
{
a.store(bb);
a.notify_one();
});
a.wait(aa);
Due to the use of std::atomic_ref, store() overwrites aa with the value of bb.
If the notify_one() call completes before the wait() call, wait() blocks
because aa == bb (due to the previous store()), and the wakeup never happens
because wakes are not queued.
