--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed.  Bisection points to r243178 (gcc 7.0.0):

r243178 | jason | 2016-12-02 08:58:32 -0500 (Fri, 02 Dec 2016) | 2 lines

        * call.c (add_function_candidate): Also exclude inherited ctors
        that take a type reference-related to the derived class.
