In my computer this stucks on string 2147503689. Also tested on g++ version

#include <algorithm>
#include <iostream>
#include <string>

using namespace std;

int main()
{
    string s = "1234567890";
    do {
      cout << s   << endl;
      stoi(s.substr(0, 10));
    }
    while (std::next_permutation(s.begin(), s.end()));
}
