--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I think it is choosing the wrong v.
Here is a testcase which shows why:
#include <iostream>
using namespace std;
class a {
protected:
int v{0};
};
class b : public a { };
class c : private a { };
class d : public c, public b {
public:
d() {
cout << b::a::v << "\n";
}
};
int main() {
d testcase{};
}
--- CUT ---
Here I qualify which a I am talking about but GCC still says:
t99.cc: In constructor ‘d::d()’:
t99.cc:13:17: error: ‘a’ is an ambiguous base of ‘d’
cout << b::a::v << "\n";
^
Confirmed.
