            Bug ID: 23657
           Summary: no matching constructor for initialization of 'string'
                    (aka 'basic_string<char>')
           Product: clang
           Version: 3.5
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org
          Reporter: apyszczuk at gmail.com

#include <iostream>
#include <string>

using namespace std; 

class Foo { 
public:
    operator string() const { return n; }
    string n {"foo"};
};

int main (int argc, char** argv) {

    string s {Foo{}}; // Error
//    string s (Foo{}); // Ok

    cout << s << endl;

    return 0;
}

main.cpp:14:12: error: no matching constructor for initialization of 'string'
(aka 'basic_string<char>')
    string s {Foo{}}; // Error
           ^ ~~~~~~~

I asked about this on stackoverflow (link added below) and someone replied that
it possibly can be a clang bug, so I posted it here. Is this a bug? gcc 4.8.3
compiles it.
