memory_order deve essere uno dei std::memory_order_relaxed, std::memory_order_consume, std::memory_order_acquire o std::memory_order_seq_cst. In caso contrario, il comportamento non è definito.

Original:

memory_order must be one of std::memory_order_relaxed, std::memory_order_consume, std::memory_order_acquire or std::memory_order_seq_cst. Otherwise the behavior is undefined.
