The sample code below produces the following internal compiler error: unique_A.f90: In function 'unique_a': unique_A.f90:42: internal compiler error: Segmentation fault
The error seems to be associated with use of the PACK() intrinsic. --CUT HERE-- function unique_A (x, sorted) result (x_unique) 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 !
