* 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 -
