Nested block variable resolution with to:do: may be incorrect

The resolution of variables in nested blocks is not correct in some cases involving to:do: optimizations.

For example, the following code returns #(nil, nil, nil, 4); the correct result is #(1 2 3 4).

  | a b |
  a := Array new: 4.
  b := Array new: 4.
  1 to: a size do: [:i |
          b at: i put: [10 timesRepeat: [a at: i put: i]]
  ].
  1 to: b size do: [:j | (b at: j) value].
  a
