closure not properly traced

[albertnetymk]

class Container<t> {
  def read() : int {
    0;
  }
}

class Main
  def main() : void{
    let bob = new Graph(10);
    bob.run();
  }

class Graph
  vat_array : [Container<int>]

  def init(size : int) : void {
    this.vat_array = new [Container<int>](size);
    for index in [0 .. |this.vat_array|-1]{
      this.vat_array[index] = new Container<int>();
    };
  }

  def run() : void {
    this ! updateEdge(1,0);
    for index in [2 .. |this.vat_array|-1]{
      let candidate = 1;
      (this.vat_array[candidate]).read() ~~> \(value : int) -> {
        this.vat_array[candidate];
      };
    };
  }

  def updateEdge(node : int, connection : int) : void {
    (this.vat_array[node]).read() ~~> \(x:int) -> { () };
  }

The memory for closures is corrupted; I see segfault within roughly 10 runs.
