The following testcase ICEs:

MODULE xc_tfw
  INTEGER, PARAMETER :: dp=8
CONTAINS
  SUBROUTINE tfw_lda_eval ( ) 
    LOGICAL                                  :: failure
    REAL(KIND=dp), ALLOCATABLE, DIMENSION(:) :: s
    REAL(KIND=dp), DIMENSION(:, :, :), POINTER :: grho, rho
    IF (.NOT. failure) THEN
       IF ( order>=2.OR.order==-2 ) THEN
          CALL tfw_u_2 ( rho, grho,  s,  error )
       END IF
         CALL cp_a_l(0==1,cp_warning_level,routineP,16)
    END IF
  END SUBROUTINE tfw_lda_eval
  SUBROUTINE tfw_p_3 ( npoints ) 
!$omp parallel do private(ip)
    DO ip = 1, npoints
    END DO
  END SUBROUTINE tfw_p_3
END MODULE xc_tfw
