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));
