You allocated a `pulsar_messages_t` object via `pulsar_messages_created()` and // let `msgs` points to this piece of memory pulsar_messages_t *msgs = pulsar_messages_create(); // 2. After `pulsar_consumer_batch_receive`, `msgs` points to another piece of memory that // is allocated inside `pulsar_consumer_batch_receive`. pulsar_result res = pulsar_consumer_batch_receive(consumer, &msgs); // 3. The memory allocated inside `pulsar_consumer_batch_receive` is deallocated. pulsar_messages_free(msgs); // NOTE: Now, the memory allocated by `pulsar_messages_created()` could never be deallocated! ``` -- This is an automated message from the Apache Git Service.
