array_uintersect (and other intersect-functions with callback) maybe link wrong..
the callback get some data a second time or nothing
or it gets 2 from the same array


Test script:
---------------
function compTest($first, $second)
{
 echo "<br> first:".$first." second: ".$second;
 if($first == $second) return 0;
 return 1;
}

array_uintersect(range(1,3),range(1,3),"comptest");
<hr>
array_uintersect(range(1,2),range(4,5),"comptest");

Expected result:
----------------
1->1
1->2
1->3
and so on...
_____
1->4
1->5
2->4
2->5

Actual result:
--------------
first:2 second: 1
first:3 second: 2
first:2 second: 1
first:3 second: 2
first:1 second: 1
first:1 second: 2
first:2 second: 2
first:2 second: 3
first:3 second: 3
________
first:2 second: 1
first:5 second: 4
first:1 second: 4
first:1 second: 5
