Yes, therefore it's a regression in 4.7 (ICE after error) and 4.8 (ICE only).


4.6 of course rejects it ('cleanly') with:

     class(ncb), allocatable, dimension(:) :: cb
                                                1
Fatal Error: Polymorphic array at (1) not yet supported



(Side note: The 'fatal' seems a bit strong here, but that was probably used to
suppress further error messages.)
