--- Comment #1 from m.cencora at gmail dot com --- This test assumes previous waiter implementation (I used gcc-11 available from Ubuntu 21.04), latest atomic_wait impl has the same problem, it is just that waiter is selected in a different way, and create_atomics would have to be adjusted to accordingly (e.g. allocate 49 atomics in a single vector, and 0,16,32,48 instances should share same waiter instance).
