--- Comment #11 from sandra at gcc dot gnu.org ---
There are still some bugs present with class arrays.  E.g., this test case
ICEs:

module m
  type :: t
    integer :: id
    real :: xyz(3)
  end type

contains

  subroutine testit2p(a)
    class(t), pointer :: a(..)
    print *, shape(a)
  end subroutine=20

end module

SHAPE is implemented as a library call and it's trying to copy the pointer
array to a temporary instead of just dereferencing it.  I'm looking at
replacing that logic to handle it inline same as LBOUND/UBOUND.=
