我的环境是opensuse、gcc5、clion、active-mq 3.10.0。我错过了什么吗？启动程序后出现分段错误。

    class MyTask : public CompositeTask{


    public:
        MyTask() { }

    public:
        virtual bool isPending() const override {
            cout<<"MyTask()::isPending\n";
            return true;
        }

        virtual bool iterate() override {
            cout<<"MyTask()::iterate\n";
            return false;
        }


    };


    class RR{
        CompositeTaskRunner compositeTaskRunner;
    public:
        RR(){


              CompositeTask* m = new MyTask();
                compositeTaskRunner.addTask(m);
            }
            void start(){
                compositeTaskRunner.start();

            }


        };

main(){

      RR* runner = new RR();
      runner->start();

}

valgrind 的输出

在使用该库之前，您必须调用其初始化方法，以准备管理资源所需的所有内部构造。

    activemq::library::ActiveMQCPP::initializeLibrary();
