* Date:    01 Feb 2002
* SUMMARY: Testing Error.length
* See http://bugzilla.mozilla.org/show_bug.cgi?id=123002
*
* NOTE: Error.length should equal the length of FormalParameterList of the
* Error constructor. This is currently 1 in Rhino, 3 in SpiderMonkey.
*
* The difference is due to http://bugzilla.mozilla.org/show_bug.cgi?id=50447.
* As a result of that bug, SpiderMonkey has extended ECMA to allow two new
* parameters to Error constructors:
*
* Rhino:        new Error (message)
* SpiderMonkey: new Error (message, fileName, lineNumber)
*
* NOTE: since we have hard-coded the length expectations, this testcase will
* have to be changed if the Error FormalParameterList is ever changed again.
*
* To do this, just change the two LENGTH constants below -
