 *
 * 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)
