          Severity: normal

          Assignee: unassigned at gcc dot gnu.org
          Reporter: egor.pugin at gmail dot com
  Target Milestone: ---

struct a {
    operator auto() { return 1; }
};
struct b : a {
    using a::operator auto;
};

gives

    5 |     using a::operator auto;

Also see following test cases.

===

ok for gcc

struct a {
    operator auto();
};
struct b : a {
    using a::operator auto;
};

===

not ok for gcc&clang, ok for msvc

struct a {
    operator auto();
};
struct b : a {
    using a::operator auto;
};

int main(){b v;int x = v;}
