This works:

                           self changed:#counterString';
              new.

(UITheme builder newColumn: {

UITheme builder newLabelFor: counter getLabel: #counterString getEnabled: nil.

  UITheme builder newRow: {

UITheme builder newButtonFor: counter action: #increment label: '+' help: nil. UITheme builder newButtonFor: counter action: #decrement label: '-' help: nil.

  }
}) openInWindowLabeled: 'Counter example'.



This one crashes the VM (tried on PharoOneClick 1.2 OSX, Cog and StackVM):

(Class new
  superclass: StringMorph;
  compile: 'step self contents: Time now printString';
  new)
    openCenteredInWorld



Any idea ?
