Re: [Pharo-project] latest build yields stack trace running #cleanUpForProduction

Here's the fix: I reverted MethodDictionary>>#compact to its previous version: compact "Make sure that I have the highest possible load factor (at least 50%)." self become: self compactWithoutBecome The non-working version was: compact "Make sure that I have the highest possible load factor (between 37.5% and 75%)." | newInstance | newInstance := self compactWithoutBecome. newInstance capacity = self capacity ifTrue: [ self copyFrom: newInstance ] ifFalse: [ self becomeForward: newInstance ] After reverting, #cleanUpForRelease worked without problem.
