Hi, In http://www.boost.org/doc/libs/1_53_0/doc/html/atomic/usage_examples.html#boo... I see that pop_all_reverse() is implemented as: node * pop_all_reverse(void) { return head_.exchange(0, boost::memory_order_consume); } Shouldn't the memory order be memory_order_acquire in this example? If I'm not mistaken, at least an acquire is required to see all the writes from the thread that did the release. GCC 4.8 also complains that memory_order_consume is not a correct memory ordering for exchange. Thanks
