             Bug #: 55017

           Summary: [C++11] Rvalue-reference member should cause copy

                    constructor not deleted, but still declared

    Classification: Unclassified

           Product: gcc

           Version: 4.8.0

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: c++

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

        ReportedBy: daniel.krueg...@googlemail.com





Using gcc 4.8.0 20121014 (experimental) with the compiler flags



-Wall -pedantic -std=c++11



the following code is incorrectly accepted:



//----------------------

struct S {

  int&& rr;

  S(int&& rr) : rr(static_cast<int&&>(rr)) {}

};



S s1(13);

S s2 = s1; // Should be rejected

//----------------------



This code should be rejected, because a non-static rvalue-reference member

causes the copy-constructor to be deleted as of 12.8 p11 b5. (Note: Even though

12.8 is currently under investigation bei CWG, there are no intentions to

change this part of the wording)
