Details:

The attached class produces the error

error: mark_as_constructed: invalid object

e.g. for the call M=MAC(2).

To fix the problem one can do the following, although I am not sure whether
the solution is correct:

In libinterp/octave-value/cdef-object.h and in

  class cdef_object_array : public cdef_object_base

one can add

  void mark_as_constructed (void) { }
  void mark_as_constructed (const cdef_class& cls) { }


In any case, the original virtual functions do not seem to be overloaded
correctly for "arrays of classes".
