--- Comment #1 from m.cencora at gmail dot com ---
This test assumes previous waiter implementation (I used gcc-11 available f=
rom
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).=
