@xiaoxiang781216 please see the latest issue: https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_barrier_destroy.html It says (at the bottom): > The [EBUSY] error for a barrier that is in use or an already initialized barrier object is removed; this condition results in undefined behavior. EDIT: It also says: > If an implementation detects that the value specified by the barrier argument to pthread_barrier_destroy() or pthread_barrier_init() refers to a barrier that is in use (for example, in a pthread_barrier_wait() call) by another thread, or detects that the value specified by the barrier argument to pthread_barrier_init() refers to an already initialized barrier object, it is recommended that the function should fail and report an [EBUSY] error. -- This is an automated message from the Apache Git Service.
