* 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!
