michael@0:  * SUMMARY:  Invoking try...catch through Function.call
michael@0:  * See  http://bugzilla.mozilla.org/show_bug.cgi?id=49286
michael@0:  *
michael@0:  * 1) Define a function with a try...catch block in it
michael@0:  * 2) Invoke the function via the call method of Function
michael@0:  * 3) Pass bad syntax to the try...catch block
michael@0:  * 4) We should catch the error!
