--- Comment #1 from G. Steinmetz <gscfq@t-online.de> ---

Variant z2.f90 with reversed order always compiles,
for every tested release, with and without -std=3Dlegacy :
(but no explicit interface, so error expected)


$ cat z2.f90
program p
   integer, pointer :: z(:) =3D> null()
   call s(null(z))
   call s(z)
end

$ gfortran-13-20221106 -c z2.f90
$ gfortran-13-20221106 -c z2.f90 -std=3Dlegacy


Test cases with an explicit interface and specified pointer dummy (ok) :

$ cat z1c.f90
program p
   integer, pointer :: z(:) =3D> null()
   call s(z)
   call s(null(z))
contains
   subroutine s(x)
      integer, pointer :: x(:)
   end
end

$ cat z2c.f90
program p
   integer, pointer :: z(:) =3D> null()
   call s(null(z))
   call s(z)
contains
   subroutine s(x)
      integer, pointer :: x(:)
   end
end=
