             Bug #: 55166

           Summary: c++11: std::string and =std:move  makes swapping

    Classification: Unclassified

           Product: gcc

           Version: 4.7.1

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: c++

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: lis...@lisp2d.net





While moving std::string value to another place g++ makes something different.



std::string t0{"abc"};

std::string t1{"123"};



t0 = std::move(t1); or t0  = static_cast<std::string  &&>(t1);



is the same result as 



std::swap(t0,t1);
