--- Comment #7 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
Compiles if "size" is replaced with synonym "product(shape)".


$ cat z5.f90
module m
  type t
  end type
contains
  function foo(a, b) result(add)
    class(t), intent(in) :: a(:)
    class(t), intent(in) :: b(product(shape(a)))
    type(t) :: add(product(shape(a)))
  end function
end module

program p
  use m
end program

$ gfortran-6 -g -O0 -fcheck=all z5.f90



$ cat z6.f90
module m
  type t
  end type
contains
  function foo(a, b) result(add)
    class(*), intent(in) :: a(:)
    class(*), intent(in) :: b(product(shape(a)))
    type(t) :: add(product(shape(a)))
  end function
end module

program p
  use m
end program

$ gfortran-6 -g -O0 -fcheck=all z6.f90



Remark:
This workaround may or may not work for production codes, it depends.
