OK, I checked again, and find top-of-the-branch r9 generating questionable
code.

  print *, g(x%len)

generates

      D.3874 = g (&(integer(kind=4)) _x, _x);

(note the 2 arguments), while

  print *, g(len(x))

generates

      D.3876 = (integer(kind=4)) _x;
      D.3877 = g (&D.3876);

which is how it should have been.
