      9 * SUMMARY:  Invoking try...catch through Function.call
     10 * See  http://bugzilla.mozilla.org/show_bug.cgi?id=49286
     11 *
     12 * 1) Define a function with a try...catch block in it
     13 * 2) Invoke the function via the call method of Function
     14 * 3) Pass bad syntax to the try...catch block
     15 * 4) We should catch the error!
