contains

--- Comment #7 from G. Steinmetz  ---

Yes, call s(z) is valid in z1, but is necessary to trigger
the ICE somehow with -std=legacy and null().

Yes, 15.4.2.2(3) was it, explicit interface of the callee with
all the characteristics of that procedure(subr/func) and dummies.

Two things are mixed here.. The following is e.g. handled correctly,
with a different error, but rejected without an explicit interface:

$ cat z3.f90
program p
   call s(null())
end

$ cat z3c.f90
program p
   call s(null())
contains
   subroutine s(x)
  integer, pointer :: x
   end
end

$ cat z3i.f90
program p
   interface
  subroutine s(x)
 integer, pointer :: x
  end
   end interface
   call s(null())
end

--- Comment #5 from G. Steinmetz  ---

I had in mind Fortran 2018, 15.4.2.2 Explicit interface,
and therefore had added the examples z1c.f90 and z2c.f90.

Some other compilers (via Compiler Explorer) show an error 
for both z1.f90 and z2.f90 :

latest flang-new :
error: Semantic errors in /app/example.f90
error: Null pointer argument requires an explicit interface
 call s(null(z))

latest ifort/ifx :
error #8615: Intrinsic NULL() is passed as actual argument. An explicit
interface specifying that the corresponding dummy is pointer, allocatable or
optional is required.
   call s(null(z))

Would be interesting what e.g. NAG and Cray say about it.

--- Comment #1 from G. Steinmetz  ---

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


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

$ gfortran-13-20221106 -c z2.f90
$ gfortran-13-20221106 -c z2.f90 -std=legacy


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

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