声明列表时的std :: bad_alloc C ++

Question

I'm trying to play around with lists and create a list of lists that contain integers. After I run the code it thorws a bad alloc exception:

"aterminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information."

#include <iostream>
#include <list>
#include <string>

int main() {
    std::list<int> l{1,2,3,4};//
    std::list<int> l1{5,6,7,8};
    std::list<std::list<int>> ll;// list of lists<int>
    std::cout << "a"; //does not reach here, terminated before this row
    ll.push_back(l);
    ll.push_back(l1);
    std::list<std::list<int>>::iterator itr;
    for (itr=ll.begin(); itr != ll.end(); itr++)
    {
        std::list<int>tl=*itr;
        std::list<int>::iterator it;
        for (it=tl.begin(); it != tl.end(); it++)
        {
            std::cout<<*it;
        }
        std::cout<<std::endl<<"End"<<std::endl;
    }
    return 0;
}

I'm running it in Clion on Windows 10 with minGW. How can I fix this? everything seems right.

I compiled you code inside of Visual Studio 2015. Your code compiled with no errors and the output was as follows.
