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

程序运行系统：CentOS7
崩溃截图如下：
下面是GDB的调用堆栈信息：

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！
发一下没用registerMessageListener函数的代码
掉用
registerMessageListener函数的代码
try
{
m_consumer_handler = new DefaultMQPushConsumer(m_consumer_group_name);
m_consumer_handler->setNamesrvAddr(m_namesrv_addr);
m_consumer_handler->setGroupName(m_consumer_group_name);
m_consumer_handler->setConsumeFromWhere(CONSUME_FROM_LAST_OFFSET);
m_consumer_handler->subscribe(m_consumer_topic, "*");
m_consumer_handler->setConsumeThreadCount(1);
m_consumer_handler->setConsumeMessageBatchMaxSize(31);
m_consumer_handler->setAsyncPull(true);
m_consumer_msg_listener = new ConsumerMsgListener(this);
m_consumer_handler->registerMessageListener(m_consumer_msg_listener);
m_consumer_handler->start();
}
catch (const MQClientException &e)
{
LOG_ERROR(e.what());
return false;
}
@HUHANK /home/code/share/mq/mf_rocketmq.cpp:32 这行代码是什么？
@HUHANK /home/code/share/mq/mf_rocketmq.cpp:32 这行代码是什么？
@HUHANK CRocketMQMessageHandler类型的定义，和运行时m_msg_handler成员变量的值是什么呢？
看起来m_msg_handler没有指向一个完整的类型。
没有指向一个完整的类型
嗯，我再测一下，把m_msg_handler相关代码从ConsumerMsgListener拿掉试试
@ifplusor
请问，我怎么样调整vector的大小，我测试发现默认size都是1，要通过那个设置函数设置这个的大小。
该问题是我代码的问题，与rocketmq-client-cpp-2.2.0的api无关，谢谢 @ifplusor 的指点。
@ifplusor 请问，我怎么样调整vector的大小，我测试发现默认size都是1，要通过那个设置函数设置这个的大小。
目前不支持，硬编码了1
