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.
