I was thinking of C++ code where you might write: template A(const T& t); A(const A& rhs); in which case A(const A&) would be chosen. I didn't realise that the rvalue reference puts a spanner in the works. I was reading the part about a template function and a non-template function being candidates, and if the non-template function is no worse than the template function then it is chosen. But I didn't realise that in this case the non-template one is actually worse. I suppose that the bug can probably be marked as invalid then.
