[Bug fortran/17192] Functions returning character pointer via argument are broken

It does still compile, but does still not return the right answer. The problem
disappears if "integer" is used instead of "character*5". The tree dump
(obtained with -fdump-tree-original) is:

s (__result, .__result, e, d, _e, _d)
{
  _gfortran_copy_string (5, e, 5, d);
  __result = (char[1:5] * &) &c;

MAIN__ ()
{
  char c[1:5];
  char[1:5] * p;
  static void s (char[1:5] * &, int4, char[1:5] &, char[1:5] &, int4, int4);

  _gfortran_copy_string (5, &c, 5, "Hallo");
  p = (char[1:5] *) &c;
  {
    char str.0[5];

    s ((char[1:5] *) &str.0, 5, &c, p, 5, 5);
    _gfortran_copy_string (5, &c, 5, (char[1:5] *) &str.0);
  }
 /* ...snip... call output routines */
}
