New issue 6850 by [hidden email]: Adding instance variable to  
superclass bug
http://code.google.com/p/pharo/issues/detail?id=6850

Evaluate this in workspace (you can do step by step if you want):

Object subclass: #Foo
        instanceVariableNames: ''
        classVariableNames: ''
        poolDictionaries: ''
        category: 'BBB'.

Foo subclass: #Bar
        instanceVariableNames: 'x'
        classVariableNames: ''
        poolDictionaries: ''
        category: 'BBB'.

Object subclass: #Foo
        instanceVariableNames: 'x'
        classVariableNames: ''
        poolDictionaries: ''
        category: 'BBB'.

the last one introduces 'x' variable into superclass,
and classbuilder swallows the new definition without any error, leading to  
two instance variables with same name in Bar subclass.

Bar allInstVarNames #('x' 'x')
