--- Comment #1 from Ted_lion <tedlion_tang at foxmail dot com> ---
I found my program blocked and it turned out to be the same problem of
atomic::wait. According to the C++20 Standard, the function atomic::wait sh=
ould
perform an atomic waiting operations. The subprocedure of comparison with o=
ld
value and waiting for the notification should not be interrupted by an
operation on same atomic object.=
