>Description:
With a default value for a template parameter it is possible to access private elements. In the example below you get access to the private class "A::type".
The compile doesn't realize or ignores the private access.
>How-To-Repeat:
class A{
private:
class type{};
};
template<class A,class type=typename A::type>
class B{
type v;
};
int main(){
// B<A,A::type> b1; doesn't work -> ok
B<A> b; //not ok
}
