* 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!
