--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I think so too; I'm afraid there's no heuristic I could implement.  You can
disable the warning for this class using:

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wdangling-reference"
struct A {
  int * i;
  int & b() { return *i; }
};
#pragma GCC diagnostic pop
