When adding an instVar on a class that is already present on a superclass, an error is reported.

However, when adding an instVar that is already present on a subclass, no error is reported.

Steps to reproduce

  1. Create a class Dummy
  2. Create a subclass DummySubclass
  3. Add an instVar myVar on DummySubclass
  4. Add an instVar myVar on Dummy

Expected behavior

An error is reported in step 4.

Actual behavior

No error is reported.
