[Bug c++/12970] New: Strange class member access rules

["v dot haisman at sh dot cvut dot cz" <gcc-bugzilla at gcc dot gnu dot org>]

This simple C++ program gives the following error which seems strange to me. GCC
3.3.1 compiles it fine.

$ g++ -W -Wall -o test test.cxx
test.cxx: In member function `void B<T>::foo(int)':
test.cxx:14: error: `x' undeclared (first use this function)
test.cxx:14: error: (Each undeclared identifier is reported only once for each f
unction it appears in.)

template <typename T>
class A
{
protected:
  int x;
};

template <typename T>
class B : public A<T>
{
public:
  void foo (int _x)
  {
    x = _x;
  }
};

int main ()
{
  B<int> b;
  b.foo(1);
  return 0;
}
