From code AudioStreamAAudio::internalErrorCallback, it will try to promote the weak pointer to a shared pointer when there is an error callback. When the shared pointer exists, it will use the shared pointer for the error callback. Otherwise, it uses the raw pointer for the error pointer. My question here is that will there be a case that the client release the shared pointer before the error callback promote from the cached weak pointer? If that is the case, it looks like there can be crash happen as the raw pointer is also invalid.
