<pre>This valid program (accepted by GCC):
```
template<class T> struct A {
typedef int M;
struct B {
typedef void M;
struct C;
};
};
template<class T> struct A<T>::B::C : A<T> {
M m; // must be OK, A<T>::M
};
```
produces an error in Clang, because it takes M from A<T>::B instead of expected
A<T>. Demo: <a href="https://gcc.godbolt.org/z/cMTYboP1Y">https://gcc.godbolt.org/z/cMTYboP1Y</a>
