为什么我不能在while循环中创建线程？

Question

I want to create a new thread inside a while loop but it makes the program instantly crash on start. Any ideas on how to fix this?

#include <thread>
using namespace std;

void function1()
{

}

int main()
{
    while(true)
    {
        thread thread(function1);
    }
    return 0;
}

When your std::thread goes out of scope, its destructor is called. The std::thread destructor calls std::terminate() if the thread is still active. You MUST join() or detach() the std::thread object before it is destroyed.
