void f(A &&a)

{

    std::move(a).p();

}



_Z1fO1A:

        .cfi_startproc

        jmp     _ZNR1A1pEv@PLT  #

        .cfi_endproc



Then this looks like a bug in 4.8.1.



But then are we in agreement that a.p() in that function above should call the

lvalue-ref overload? It does make the feature sligthly less useful for me. It

would require writing:



    return std::move(std::move(std::move(std::move(QString("%1 %2 %3 %4")

                                                   .arg(42))

                                          .arg(47))

                               .arg(-42))

                     .arg(-47));
