Following code:

struct X
{
    void f();
};

struct Y
{
    void f();
};

template <typename Base>
struct A : Base, X {
  virtual void foo()
  {
    f();
  }
};

int main()
{
    A<Y> t;
}

gives error message:
j_test.cpp: In member function `void A<Base>::foo() [with Base = Y]':
j_test.cpp:21:   instantiated from here
j_test.cpp:16: error: request for member `f' is ambiguous
j_test.cpp:4: error: candidates are: void X::f()
j_test.cpp:9: error:                 void Y::f() = Y]':

Even though the dependent base should not be considered.
This seems to happen only when foo is virtual and f is found from 
non-dependent base.
