--- Comment #3 from anlauf at gcc dot gnu.org ---
Interestingly, when using the RESULT clause in the function declaration,
the evaluation of SIZE appears to work for:

program bug
  implicit none
  real :: u(3)
  u =3D f(3)
  u =3D g(3)
contains
  !-
  function f(n)
    integer, intent(in) :: n
    real    :: f(n)
    integer :: y(size(f))
    f =3D 1
    print *, 'f: size(y) =3D',size(y)
  end function f
  !-
  function g(n) result (f)
    integer, intent(in) :: n
    real    :: f(n)
    integer :: y(size(f))
    f =3D 2
    print *, 'g: size(y) =3D',size(y)
  end function g
end

This prints:

 f: size(y) =3D           0
 g: size(y) =3D           3

(Expecting size=3D3 in both cases).=
