 * SUMMARY:  Invoking try...catch through Function.call

 * See  http://bugzilla.mozilla.org/show_bug.cgi?id=49286

 * 1) Define a function with a try...catch block in it

 * 2) Invoke the function via the call method of Function

 * 3) Pass bad syntax to the try...catch block

 * 4) We should catch the error!
