Do memory leaks occure in this code???

[reptile]

#include <iostream>
#include <string>
using namespace std;

class Class {
public:
    string s;
    
    string get_s()
    {
         static string _s = s;
         return _s;
    }
};

int main()
{
    Class c;
    c.s = "Hello world";
    cout << c.get_s().c_str();
}
