Problem description

A class which sub-classes another class with the same name crashes Octave.

To recreate the issue save the following into crashoctaveclass.m


classdef crashoctaveclass<crashoctaveclass
  methods
    function crashoctaveclass()
    endfunction
  endmethods
endclassdef


Octave will crash when the constructor is called:

crashoctaveclass()

What I expect should happen

If crashoctaveclass does not exist in the path I would expect an error message
telling me that the class I'm trying to subclass does not exist. If it does
exist I would expect my new class to be a subclass of the other class in the
path.
