Confirmed. This issue is still present on the development branch. I have changed the category to Matlab Compatibility.

I lowered the priority by 1 since there is a workaround.

I have a simple class hierarchy with two classes:

  • In the base class, the constructor calls a method which initializes some properties.
  • In the derived class, I override said method (while still calling the parent method). The constructor also invokes the parent constructor.

Here is a minimal example:

$ cat ClassA.m

$ cat ClassB.m

This works fine in MATLAB (I'm using R2017a):

But it fails in Octave 4.2.1:

I did try to incorporate the functionality of the foo method into the constructor (i.e directly set the properties a and b from the respective constructors), and the code does work then (both MATLAB and Octave):

$ cat ClassAA.m ClassBB.m

Still, I wanted to report this case... Thanks.
