[I] when i use [rocketmq-client-cpp-2.2.0] api in my app, it's often Crashed with Error: pure virtual method called [rocketmq-client-cpp]

HUHANK opened a new issue, #465:
URL: https://github.com/apache/rocketmq-client-cpp/issues/465

   **程序运行系统**：CentOS7
   
   **崩溃截图如下**：

   **下面是我的关键代码片段**：
   ```
         class ConsumerMsgListener : public MessageListenerOrderly
         {
         public:
             ConsumerMsgListener(CRocketMQMessageHandler *phandler) : 
m_msg_handler(phandler)
             {
             }
             virtual ~ConsumerMsgListener() {}
         
             ConsumeStatus consumeMessage(const vector<MQMessageExt> &msgs) 
override
             {
                 for (size_t i = 0; i < msgs.size(); i++)
                 {
                     shared_ptr<BusMessage> pBusMsg = make_shared<BusMessage>();
                     pBusMsg->fromJson(msgs[i].getBody());
                     if (m_msg_handler)
                     {
                         if (!m_msg_handler->messageHandle(
                                 pBusMsg, msgs[i].getQueueId(),
                                 msgs[i].getQueueOffset()))
                         {
                             return RECONSUME_LATER;
                         }
                     }
                     else
                     {
                         return RECONSUME_LATER;
                     }
                 }
                 return CONSUME_SUCCESS;
             }
         private:
             CRocketMQMessageHandler *m_msg_handler = nullptr;
         };
   ```
   个人觉得是官方API的BUG，如果有大神遇到过类似问题，并解决的希望不宁赐教，请官方确认一下这个问题，谢谢！
