Description:
------------
This was discovered by another guy who asked me to verify it on my configuration (and I confirmed it). I'm not sure he reported it, so just in case I do as well.

The example source code produced 989, 377, 989, 377 from rand() ad infinitum under Windows XP, Apache 2.2, PHP 5.2.6.

Important:

- Linux apparently not affected.
- mt_rand() apparently not affected.

Reproduce code:
---------------
function RandomNumber() {
	$f1 = array();

	for ($i = 0; $i < 50000; $i++) {		
		$f1[] = true;
	}	
			
	$k = array_rand($f1);
	
	$rnum = rand(1,999);	
	
	return $rnum;
}

for ($i = 0; $i < 20; $i++) {
	
	echo RandomNumber()."\n"; // produces a sequence of 377, 989, 377, 989, 377, 989, 377...  here
}

Expected result:
----------------
Random numbers.

Actual result:
--------------
Same number or narrow repeated sequence.
