--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Here's a case where I think the warning is too noisy:
template<typename T>
class trait
{
template<typename U>
static U get();
public:
using type = decltype(get<T>());
};
trait<int> i;
When compiled with -Wctor-dtor-privacy this warns:
tr.cc:2:7: warning: all member functions in class 'trait<T>' are private
[-Wctor-dtor-privacy]
2 | class trait
| ^~~~~
The member function is supposed to be private. It's used by the
typedef-declaration, but only the typedef needs to be public.
The documentation for the warning says "Also warn if there are no non-private
methods, and there's at least one private member function that isn't a
constructor or destructor." I think the warning should be suppressed if those
private member functions are used by a public typedef.
