           Summary: [5 Regression] ICE: tree check: expected ssa_name,
                    have var_decl in walk_aliased_vdefs_1, at
                    tree-ssa-alias.c:2689
           Product: gcc

On ppc64 I get:

  {
    AddObserver (p1, p2, p3);
  }
};

class F : C

  nsresult Install ();

nsresult

  for (int i;;)
    branch->AddObserver (prefList[i], this, false);
}
