Exactly. The point is that the standard says "The usual qualified name
lookup (3.4.3) is used to find the qualified-id even in the presence of
typename."

The test is supposed to be invalid, but should give an error on line 6 and line
7, GCC only gives an error on line 7.

Your reduced version is irrelevant because it's not a template and there's no
"typename" keyword. GCC gets that right, but doesn't get the original report
right.
The test can be reduced to this, which should not compile:
struct A {
struct X { };
int X;
};
template<class T> void f(T t) {
typename T::X x;
}
void foo() {
A a;
f(a); // error: T::X refers to the data member A::X not the struct A::X
}
