Interestingly, following invalid variant with "type(t)"
is silently accepted and gives same results as z0.f90 in comment 1.
$ cat z2.f90
program p
type t
integer :: n
end type
type(t) :

Detected with type "real" instead of "class(t)" :
$ cat z3.f90
program p
type t
integer :: n
end type
real :: g !!

subroutine h
end
end interface

Backtrace identical to that of pr68846 comment 3 etc.

Further modified and reduced to a skeleton, i.e. :

module m68846
type t
contains
procedure, nopass :: f => f1
end type
contains
function f1() result(p)

Both variants reduced and simplified a bit :

module m68846
type grid_t
real, pointer :: p(:) => null()
end type
type subgrid_t
class(grid_t), pointer :: grd => null()

Whereas, for example with "real" :
$ cat z2.f90
program p
type t
real :: c(1) = [t()]
end type
end
$ gfortran-7-20161204 z2.f90

character(3) :: c2(2) = ['b', 'c'] // 'a'
character(3) :: c3(2) = ['b', 'c'] // 'ax'
