--- Comment #17 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-01-11 15:53:51 UTC ---
On the trunk, when optimizing, we now inline the nested function and
optimize everything away.  Adjusted testcase:

int
main (int argc, char **argv)
{
  int size = 10;
  typedef struct
    {
      char val[size];
    }
  block;
  block b;
  block __attribute__((noinline))
  retframe_block ()
    {
      return *(block *) &b;
    }
  b=retframe_block ();
  return 0;
}

which makes this a dup of PR8081.
