FYI, a directly matching variant compiles :

$ cat z2.f90
program p
   type t
      procedure(g), pointer :: f
   end type
   class(t), allocatable :: z
   call s(z%f)
contains
   subroutine g(x)
      class(t) :: x
   end
   subroutine s(x)
      procedure(g) :: x
   end
end

Also GCC 4.8 ICEs.

FWIW, it is -fcheck=pointer triggering the ICE.

Fix for this PR

Thanks for the report. The attached does what is required, I believe. It is
regtesting as I write.
