--- Comment #2 from Kaelyn Takata <rikka at google.com> ---
This appears to be fixed. As of r236883, the example:

struct S { int i; };
struct T { S* get_s(); };
int f(S* s) {
  T t;
  return t.get_s
      .i;
}

yields:

zbugs.cc:5:12: error: reference to non-static member function must be called;
did you mean to call it with no arguments?
  return t.get_s
         ~~^~~~~
                ()
zbugs.cc:6:7: error: member reference type 'S *' is a pointer; did you mean to
use '->'?
      .i;
      ^
      ->
2 errors generated.

And the example with Nick's replacement line yields:

zbugs.cc:5:30: error: reference to non-static member function must be called;
did you mean to call it with no arguments?
  return      t       .      get_s      .i;
              ~~~~~~~~~~~~~~~^~~~~
                                  ()
zbugs.cc:5:41: error: member reference type 'S *' is a pointer; did you mean to
use '->'?
  return      t       .      get_s      .i;
              ~~~~~~~~~~~~~~~~~~~~      ^
                                        ->
2 errors generated.
