[Bug fortran/41872] New: wrong-code: No auto-deallocation for INTENT(OUT) allocatable scalars

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following programs shows that the automatic deallocation is not applied to
allocatable INTENT(OUT) scalar dummies. It works for array arguments.

Note: For optional arguments, one needs to make sure that the deallocation only
happens if the variable is present, cf. PR 41850.

program test
  implicit none
  integer, allocatable :: a
  allocate(a)
  call foo(a)
  if(.not. allocated(a)) call abort()
  if (a /= 5) call abort()
contains
  subroutine foo(a)
    integer, allocatable, intent(out) :: a
    if(allocated(a)) call abort()
    allocate(a)
    a = 5
  end subroutine foo
end program test
