/* * Date: 24 September 2001 * * 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)
