Subject: Array disorder in ruby 1.8.6

Hello,

I suppose I found a bug in ruby (or behavior that I am unable to
explain). My version is, exactly, ruby 1.8.6 (2007-03-13 patchlevel 0)
[universal-darwin8.0]

problem is in this method:

def plotresults(results,runset)
        ...
  runset.each{|k| f.printf("%-*s",ns,k)}
        ...
end

.each iterator just prints the items of the runset array out of order.
however, if I just evaluate the array anywhere in the method, everything
is ok:

def plotresults(results,runset)
        runset
        ...
  runset.each{|k| f.printf("%-*s",ns,k)}
        ...
end

Not much more to say about that. Can anybody explain to me why Ruby
should behave like that?
