Wrong inspection - expression must be rvalue

I'm using quite a lot of list in my app and see a wrong inspection which flags as an error. Below a short code snippet to explain it.

In the first while loop the code shall copy the returned reference to a string variable. Actually the compiled code is OK and works, however CLion flags it with expression must be rvalue which is wrong. C++ in this case copies the value from the referenced item to the variable, thus no warning necessary. I checked the known issues, however not found this case (maybe hidden in the two other issues that deal with rvalue).

In the second while loop I use a reference, the inspection error message is gone, however the code does not work anymore. The pop_front() removes the string from the list and thus the reference is gone. This is a simplified example, the real loop is more complex :-) .

As an interesting experiment: enable the string name; on top of the first while loop (remove the //) and then the wrong inspection is also gone :-) . Well, in this case I have the warning that a local variable hides a variable in an upper scope and this is obviously OK.

Code snippet:

shared_ptr<list<string> > func1() {
    shared_ptr<list<string> > lst = make_shared<list<string> >();
    string tst("testing-1");
    lst->push_back(tst);
    tst = "testing-2";
    lst->push_back(tst);
    return lst;
}

int main() {

    shared_ptr<list<string> > names = func1();

    size_t size = names->size();
    cout << "List size - 1 : " << size << endl;

//    string name;
    while (!names->empty()) {
        string name = names->front();    // expression must be rvalue
        names->pop_front();
        cout << "name (1): " << name << endl;
    }

    names = func1();
    size = names->size();
    cout << "List size - 2 : " << size << endl;

    while (!names->empty()) {
       const string& name = names->front(); // OK, however can't use 'name' anymore after pop_front
       names->pop_front();
       cout << "name (2): " << name << endl;
    }

 return 0;
}
