! The problem was an ICE when trying to deallocate the
! result variable "x_unique".
!
function unique_A (x, sorted) result (x_unique)
implicit none
character(*), dimension(:), intent(in) :: x
logical, intent(in), optional :: sorted
character(LEN(x)), dimension(:), allocatable :: x_unique
logical :: sorted_
character(LEN(x)), dimension(SIZE(x)) :: x_sorted
integer :: n_x
logical, dimension(SIZE(x)) :: mask
integer, external :: b3ss_index
! Set up sorted_
if(PRESENT(sorted)) then
sorted_ = sorted
else
sorted_ = .FALSE.
endif
! If necessary, sort x
if(sorted_) then
x_sorted = x
else
x_sorted = x(b3ss_index(x))
endif
! Set up the unique array
n_x = SIZE(x)
mask = (/.TRUE.,x_sorted(2:n_x) /= x_sorted(1:n_x-1)/)
allocate(x_unique(COUNT(mask)))
x_unique = PACK(x_sorted, MASK=mask)
! Finish
return
