The incinerator is the API which tries to solve the “ABA problem” when related to pointer dropping. util. The queue can be any length because the storage is supplied as a mutable slice at creation time. The “default” usage of this type as a queue is to use push_back to add to the queue, and pop_front to remove from the queue. As such, calling enqueue() after emptying the queue causes pool->start->prev = node; to execute, while the node pool->start is no longer valid and potentially already free() ed.
