Does fix the ICE apparently, but then gives:

/tmp/cc6WAMPO.o: In function `__gn_MOD_ndm':
c0.f90:(.text+0x676): undefined reference to `__final_gn_Nde.2455'

Not sure, but I'll try to find out.


Btw, the following variant gives a different ICE also with the patch:


module gn
  implicit none
  type sl
     integer, allocatable, dimension(:) :: lv
   contains
     final :: sld
  end type

contains

  subroutine sld(s)
    type(sl) :: s
  end subroutine

end module


  use gn
  type :: nde
     type(sl) :: r
  end type

contains

  subroutine ndm
    type(nde) :: s,i
    i=s
  end subroutine

end
