! Various checks for the linear clause
! 5.4.6 `linear` Clause
! Case 1

subroutine linear_clause_03(arg)
integer, intent(in) :: arg
!ERROR: The list item `arg` specified with the REF 'linear-modifier' must be polymorphic variable, assumed-shape array, or a variable with the `ALLOCATABLE` attribute
