If that's of any hint/help, I get the exact same thing on latest Pharo/Spur on Windows. -----------------

I have a nice one:

In (seemingly) any 5.0 image, with the latest Spur, type the following 
in a workspace and printIt a couple of time:


(1 to: 3) collect: [:i |
    m := ''.
    2 timesRepeat: [m := m,  ('1234' perform: #copyFrom:to: with: 2 with: 4)].
    m]


I get kind of randomly either #('234' '' '') or the correct #('234234' 
'234234' '234234'), or at times #('234234' '' '').


Attached is the same code, this time in a method. It is even funkier, 
since a common answer is then 'copyFrom:to:234', although I sometimes 
get '234234' ...
