* SUMMARY: Testing that we don't crash on Array.sort()
* SUMMARY: Testing that Array.sort() doesn't crash on very large arrays
* See http://bugzilla.mozilla.org/show_bug.cgi?id=157652
*
* How big can a JavaScript array be?
* ECMA-262 Ed.3 Final, Section 15.4.2.2 : new Array(len)
*
* This states that |len| must be a a uint32 (unsigned 32-bit integer).
* Note the UBound for uint32's is 2^32 -1 = 0xFFFFFFFF = 4,294,967,295.
*
* Check:
*
* js> var arr = new Array(0xFFFFFFFF)
* js> arr.length
* 4294967295
*
* js> var arr = new Array(0x100000000)
* RangeError: invalid array length
*
