| * 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! |
