There's more to it. When generate wrong-code for optional arguments, as shown
by the following code:

$ cat b.f90 
program trs
  implicit none
  integer :: size, ierr
  integer, allocatable, dimension(:) :: seed
  call random_seed(size)
  allocate(seed(size), stat=ierr)
  if (ierr /= 0) stop
  call test_random_seed()
contains
  subroutine test_random_seed(get)
    integer, dimension(:), optional :: get
    call random_seed(get=get)
  end subroutine test_random_seed
end program trs
$ gfortran b.f90 && ./a.out
Segmentation fault
