eventscript.js

var sys = require('sys');
var EventEmitter = require('events').EventEmitter;
var Script = process.binding('evals').Script;

function EventScript(code, filename) {
  this.code = code;
  this.filename = filename;
};

sys.inherits(EventScript, EventEmitter);

EventScript.prototype.runInNewContext = function (sandbox) {
  sandbox.events = this;

  this.script = new Script(this.code, this.filename);
  this.script.runInNewContext(sandbox);

  delete sandbox.events;
};

exports.EventScript = EventScript;

Any idea why this makes node segfault?
