   This is caused by a race condition. Currently nothing prevents you from closing the client with pending async operations in flight. Closing the client ends up killing all of the boost::asio executors. This means we see async workers like ProducerNewInstanceWorker calling into pulsar_client_create_producer on a client that has either already been closed or is about to be closed. By the time it gets to invoking a certain async function, the state of the executor is invalid because it has been closed prematurely. We have to avoid invoking methods that create resources from a closed client.
