For me, the ssnippet from Stephan Eggermont works reliably well
(I mean allways fails in official 3.0 distribution for MacOSX )

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

When Transcript is opened, I never reached iteration 1000 on my mac with
official VM.
There's always an Integer that does not understand reversed in my way.
