--- Comment #4 from janus at gcc dot gnu.org 2012-04-15 19:32:22 UTC ---
Just out of curiosity: Are you aware of any compiler which swallows this?


Here is a slightly reduced test case, which gives the same ICE:

module adv
  implicit none

  type adv_t
  contains
    procedure, nopass :: left_halo
  end type 

contains

  function left_halo (arr)
    real, intent(in), dimension(:), pointer :: arr
    real, dimension(:), pointer :: left_halo
    left_halo => arr(-1:-1)
  end function

end module

program test
  use adv
  implicit none

  real, dimension(:), pointer :: arr
  class(adv_t), allocatable :: a

  allocate(adv_t::a)
  allocate(arr(-1:5))

  arr(-1) = 666
  print*, a%left_halo(arr)

  a%left_halo(arr) = -666  ! ICE

end program
