--- Comment #5 from anlauf at gcc dot gnu.org ---
The issue in comment#3 is likely unrelated to TRANSFER:

program p
  implicit none
! integer, parameter :: k =3D 1
  integer, parameter :: k =3D 4
  character(kind=3Dk,len=3D2), parameter :: z =3D k_"FG"
  character(kind=3D1,len=3D*), parameter :: x =3D transfer (z, 'abcdefgh')
  character(kind=3Dk,len=3D2)            :: u =3D transfer (x, z) ! always =
OK
  character(kind=3Dk,len=3D2), parameter :: v =3D transfer (x, z) ! OK (kin=
d=3D1)
  logical, parameter                 :: l =3D (z =3D=3D v)
  print *, "z =3D=3D v:", l
  print *, z
  print *, u
  if (u /=3D z) stop 4
  print *, v
  if (v /=3D z) stop 3  ! stops here for kind=3D4
end

This works for k=3D1 (z=3D=3Dv), but fails for k=3D4 (z/=3Dv, but should be=
 same).

(NAG confirms my expectations.)=
