  22 * SUMMARY:  Invoking try...catch through Function.call
  23 * See  http://bugzilla.mozilla.org/show_bug.cgi?id=49286
  24 *
  25 * 1) Define a function with a try...catch block in it
  26 * 2) Invoke the function via the call method of Function
  27 * 3) Pass bad syntax to the try...catch block
  28 * 4) We should catch the error!
