Test eon from SPEC CPU2000 fails to build on powerpc64-linux with both -m32 and
-m64 and "-fnon-call-exceptions -ffast-math -fno-gcse " with an ICE in
calc_dfs_tree at dominance.c:393

Minimized test case:

class One {
public:
    One () { e[0] = e[1] = 0.0; }
    double e[2];
};

template <class T>
class Two {
public:
    Two();
private:
    T *data;
    int arraySize;
};

template <class T>
Two<T>::Two() {
   data = new T[arraySize];
}

class Three {
protected:
  Two<One> data;
};

class Four : public Three {
public:
  Four ();
  void Foo (int n);
};

Four :: Four (){
   Foo (1);
}

The ICE starts with:
