79568 - delete on an arguments[i] not working correctly

Status: VERIFIED FIXED

(Rhino Graveyard :: Core, defect)

Description

[Phil Schwartau]

The following testcase is passing in SpiderMonkey, but failing in Rhino: 

               js/tests/ecma_3/Function/arguments-001.js


In Rhino : test FAILS
function g(){delete arguments[0]; return arguments[0]}
g(42)
42   //should print 'undefined'


In SpiderMonkey: test PASSES
function g(){delete arguments[0]; return arguments[0]}
g(42)
undefined  



Brendan (from bug 72884):

"Per ECMA-262, delete on an arguments[i] should succeed and remove that property  
from the arguments object, leaving any get of it after the delete to evaluate  
to undefined."
