wolfstudy opened a new issue #40: When using the go client's producer to send messages, the cgo client's consumer cannot be consumed normally.
URL: https://github.com/apache/pulsar-client-go/issues/40
 
 
   #### Expected behavior
   
   When using the go client's producer to send messages, the cgo client's consumer can be consumed normally.
   
   #### Actual behavior
   
   go client producer:
   
   ```
   func main() {
       client, err := pulsar.NewClient(pulsar.ClientOptions{
           URL: "pulsar://localhost:6650",
       })
   
       if err != nil {
           log.Fatal(err)
       }
   
       defer client.Close()
   
       producer, err := client.CreateProducer(pulsar.ProducerOptions{
           Topic: "my-topic-1",
       })
       if err != nil {
           log.Fatal(err)
       }
   
       defer producer.Close()
   
       ctx := context.Background()
   
       for i := 0; i < 10; i++ {
           if err := producer.Send(ctx, &pulsar.ProducerMessage{
               Payload: []byte(fmt.Sprintf("hello-%d", i)),
           }); err != nil {
               log.Fatal(err)
           }
       }
   }
   ```
   
   cgo client consumer:
   
   ```
   func main() {
   	client, err := pulsar.NewClient(pulsar.ClientOptions{URL: "pulsar://localhost:6650"})
   	if err != nil {
   		log.Fatal(err)
   	}
   
   	defer client.Close()
   
   	consumer, err := client.Subscribe(pulsar.ConsumerOptions{
   		Topic:            "my-topic-1",
   		SubscriptionName: "my-subscription",
   		Type:             pulsar.Shared,
   	})
   	if err != nil {
   		log.Fatal(err)
   	}
   
   	defer consumer.Close()
   
   	for {
   		msg, err := consumer.Receive(context.Background())
   		if err != nil {
   			log.Fatal(err)
   		}
   
   		fmt.Printf("Received message  msgId: %s -- content: '%s'\n",
   			msg.ID(), string(msg.Payload()))
   
   		consumer.Ack(msg)
   	}
   }
   ```
   
   cgo client receive payload content is nil.
   
   ```
   Received message  msgId: (4,0,-1,0) -- content: ''
   Received message  msgId: (4,1,-1,0) -- content: ''
   Received message  msgId: (4,2,-1,0) -- content: ''
