Description:
------------
When passing empty arrays to a function using a parameter that defaults
to null, the default value is being passed instead of the array.

Reproduce code:
---------------
function test($value=null) {
 		if($value == null) {
 			print "null";
 		} else {
 			print "not null";
 		}
 	}

	test(array());

Expected result:
----------------
"not null"

Actual result:
--------------
"null"
