*
* SUMMARY: Try assigning arr.length = new Number(n)
* From correspondence with Igor Bukanov <igor@icesoft.no>
* See http://bugzilla.mozilla.org/show_bug.cgi?id=101488
*
* Without the "new" keyword, assigning arr.length = Number(n) worked.
* But with it, Rhino was giving an error "Inappropriate array length"
* and SpiderMonkey was exiting without giving any error or return value -
*
* Comments on the Rhino code by igor@icesoft.no:
*
* jsSet_length requires that the new length value should be an instance
* of Number. But according to Ecma 15.4.5.1, item 12-13, an error should
* be thrown only if ToUint32(length_value) != ToNumber(length_value)
