Hi,

I modify the variable in the method "clonePreStartup".
So, it works fine.

=====
!SystemTracer2 methodsFor: 'clone startup' stamp: 'ajh 8/22/2002 11:15'!
clonePreStartup
	"This will be executed right away when the new clone starts up, before processStartup.  Subclasses may want to rehash all objects or something"
	SystemDictionary wordSize: self wordSize.! !
=====

Now, there are some tests which does not pass.
So, I will publish the code and the pharoImage64, and with the community, we can check this.

Cheers,
Jannik
