运行错误 terminate called without an active exception

运行错误：terminate called without an active exception，可能的原因 ：下面的代码中的 

        t41.join();
        t42.join();
        t43.join();

注释掉会出现这个错误

#include "stdio.h"
#include 
#include 

int main(int argc, char **argv){


    std::thread t1([](){
        while(true){
            std::this_thread::sleep_for(std::chrono::seconds(1));
            printf(" t1 t1 t1 t1 ------------------------------------- \n");
        }
    });

    std::thread t2([](){
        while(true){
            std::this_thread::sleep_for(std::chrono::seconds(1));
            printf(" t2 t2 t2 t2 ------------------------------------- \n");
        }
    });

    std::thread t3([](){
        while(true){
            std::this_thread::sleep_for(std::chrono::seconds(1));
            printf(" t3 t3 t3 t3 ------------------------------------- \n");
        }

                std::this_thread::sleep_for(std::chrono::seconds(1));
                printf(" t41 ------------------------------------- \n");
            }
        });

        std::thread t42([](){
            while(true){
                std::this_thread::sleep_for(std::chrono::seconds(1));
                printf(" t42 ------------------------------------- \n");
            }
        });

        std::thread t43([](){

        });
        t41.join();
        t42.join();
        t43.join();
    });

    t1.join();
    t2.join();
    t3.join();
    t4.join();

    return -1;
}

输出：

 t41 ------------------------------------- 
 t1 t1 t1 t1 ------------------------------------- 
 t2 t2 t2 t2 ------------------------------------- 
 t3 t3 t3 t3 -------------------------------------
