yeah, I did that for the final patch.  Will submit soon.

This is less of an issue.  We also currently fail on the following:

subroutine s4
  integer, parameter :: n =3D 4
  integer, parameter :: x(transfer(n, n)) =3D 1 ! legal
  integer            :: y(transfer(n, n)) =3D 2 ! legal
  integer, parameter :: k =3D size (x) ! ok
  integer, parameter :: m =3D size (y) ! fails, tracked separately
  print *, k, x, y
  if (k /=3D size (y)) stop 1
end

For some reason we do not simplify SIZE(y), and this reason lies elsewhere.
And it is not touch by my patch.

I'll bet he does, but don't hold your breath?=
