I am running into this error with Octave 5.2, the original workaround provided here has not worked in my case. 

The header file cdef-object.h was not found but I did have ov-classdef.h which contained the class

class cdef_object_array : public cdef_object_base

I added the two suggested functions and unfortunately kept on having the same error when running my script. I have also attempted to run the MAC.m script provided in this discussion.

Any help or update about this issue is appreciated.

I can confirm this error in Octave 5.2, 6.1, a current stable (hg id 8b65dc1fd34d), and default (hg id 1ece396fe3df).

The same class constructs without error with Matlab R2020b.

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".
