[ruby-talk:02496] BUg in 4-11 Ruby?

Running the following on ruby 1.5.3 (2000-04-11) [i686-linux]

    callcc {|cont|
      for i in 0..4
        print "\n#{i}: "
        for j in i*5...(i+1)*5
          cont.call() if j == 17
          printf "%3d", j
        end
      end
    }
    print "\n"

I get

    1:   5  6  7  8  9
    2:  10 11 12 13 14
