--- Comment #2 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Test case:

module newunit_bug
  implicit none

contains

  subroutine open_file_safe(fname, fstatus, faction, fposition, funit)
    character(*), intent(in)  :: fname, fstatus, faction, fposition
    integer, intent(out)      :: funit

    integer :: istat

    select case (fstatus)
      case ('scratch')
        open(newunit=funit, status=fstatus, access='sequential', &
          form='formatted', iostat=istat)
      case default
        open(newunit=funit, file=fname, status=fstatus, access='sequential', &
          form='formatted', action=faction, position=fposition, iostat=istat)
    end select

  end subroutine open_file_safe
end module newunit_bug
