--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The warning is bogus, because that type inherits a default constructor from its
base class (also it probably shouldn't give a warning for code in system
headers).
Minimal testcase:
template<typename T> struct A { };
template<typename T> struct B : A<T> {
using A<T>::A;
B(const B&) { }
};
It's probably related to constructors in dependent base classes not being seen
at the point the warning is given.
