Hence to get a rep[roducible case, that you could even look at in the
Simulator, merely evaluate

Smalltalk snapshot: true andQuit: true.
1 to: 1000 do: [ :i |
        | string |
        Transcript show: 'Iteration '; show: i; cr.
        1 timesRepeat: [
            (string := String new: 1000 withAll: $a)
                reversed.
        ].
    ].

and when you start-up the image it should crash with no user intervention.
 Voila, a reproducible case...
