--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-04-07 08:30:57 UTC ---
template<typename T>
struct A
{
  ~A ();
  T *operator-> () const;
};

struct B
{
  typedef A <B> P;
  static P foo (int);
};

struct C
{
  typedef A<C> P;
  static const int c = 80;
};

C::P bar ();

void
baz ()
{
  char z[bar ()->c];
  {
    B::P m = B::foo (sizeof (z));
  }
}

Yeah, apparently some problem on the FE side with cleanups, where
CLEANUP_POINT_EXPR already for z is given the cleanups for m, which are in a
nested bind though and thus m wasn't seen in bind expr yet.
