这是g ++错误吗？

Question

使用以下代码时

#include <iostream>
#include <vector>
#include <string>

int main()
{

    std::vector<std::string> vec;
    std::string temp{};
    while(std::cin >> temp) vec.push_back(temp);

    std::cout << "\n[ " << vec[0];
    for(int i {1}; i < vec.size(); i++) std::cout << ", " << vec[i];
    std::cout << "]";

}

使用以下输入

kghukg kjhukg 6887 ^D

我知道

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

我正在Ubuntu上使用CLion和

asmmo@asmmo:~$ g++ --version
g++ (Ubuntu 9.3.0-8ubuntu1) 9.3.0

我收到std=-s++1z和c++2a的错误

考虑到评论，我将代码更新为

#include <iostream>
#include <vector>
#include <string>
#include <thread>
using namespace std::chrono_literals;
int main()
{

    std::vector<std::string> vec;
    std::string temp{};
    while(std::cin >> temp) vec.push_back(temp);
    std::cout<<vec.size();
    std::this_thread::sleep_for(10s);
    std::cout << "\n[ " << vec[0];
    for(int i {1}; i < vec.size(); i++) std::cout << ", " << vec[i];
    std::cout << "]";

}

然后使用

kjjkj jkh 555 ^D

但是它等待了，除了错误之外什么也没显示

我的心理猜测是，这是CLion如何向程序提交输入的问题。
