// The hack for PR c++/44909 breaks this testcase. We need feedback // from the C++ committee to know how to proceed. // { dg-do compile { target c++11 } } struct A { A(); A(A&); }; struct B; struct BP { BP(const B&); }; struct B { B(); B(B&&); B(const BP&); }; // If B(B&&) suppresses the B copy constructor, then copying the B // subobject of C should use B(const BP&). But we ignore that constructor // in order to break the cycle in 44909. Perhaps the move ctor shouldn't // suppress the copy ctor? // As of DR 1082, it doesn't suppress it. struct C: A, B { }; // { dg-error "use of deleted" } C c; C c2(c); // { dg-error "deleted" }
