This is because the VM directly accesses (by offset) certain instVars of certain classes. For example, it knows that the MethodDictionary of a class is at the offset 2. So, if you add an instVar to Object all these offsets will be shifted, and VM will be accessing incorrect places, and therefore, a crash :) > > On 03.11.2012, at 15:26, Edgar J.
