excellent can you sync with marcus? We will have to clean SystemDictionary because this is not a namespace but a kind of clean trash. (when I compared to what is was). I will start to think about what we want. but in a nutshell
- a namespace class that only deals with binding (may be class Smalltalk) - a class that deals with image and VM code (may be called SmalltalkImage)

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

Ok, well I created Mantis http://bugs.squeak.org/view.php?id=7430 to document.
Personally I would do Smalltalk wordSize versus SystemDictionary wordSize
Also the issue is when to change the WordSize variable.
I think in SmalltalkImage>>snapshot: andQuit: embedded: right at the ifTrue: [self quitPrimitive]. Cursor normal show. you want to set things so that wordSize is reset.
At quit time you could do the reset before the "self quitPrimitive" then you know the value is reset and needs to be recalculated at startup time. or you can reset it before the Cursor normal show. which runs after startup time
Somehow I think there is more risk resetting it after startup since I'm not sure when something could leap in wanting a valid value.

Hi Eliot, hi John,
This is what I do: - create a class var in SystemDictionary - accessors (wordSize and wordSize:), the first one can initialize the variable if nil, the second is to modify the value in case of 64bits image. Maybe the second one could be integrated in System-Tracing file. - in CompiledMethod, initialPC use it.
Maybe we could integrate it in pharoCore.
