michael@0:  * SUMMARY: Try assigning arr.length = new Number(n)
michael@0:  * From correspondence with Igor Bukanov <igor@icesoft.no>
michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=101488
michael@0:  *
michael@0:  * Without the "new" keyword, assigning arr.length = Number(n) worked.
michael@0:  * But with it, Rhino was giving an error "Inappropriate array length"
michael@0:  * and SpiderMonkey was exiting without giving any error or return value -
michael@0:  *
michael@0:  * Comments on the Rhino code by igor@icesoft.no:
michael@0:  *
michael@0:  * jsSet_length requires that the new length value should be an instance
michael@0:  * of Number. But according to Ecma 15.4.5.1, item 12-13, an error should
michael@0:  * be thrown only if ToUint32(length_value) != ToNumber(length_value)
