While using classes, pointers and globals I noticed data not being migrated to the globalsphere due to pointerassignments.

[Example]

class test {
    var $v=0;
    function set($i) { $this->v = $i; }
}

$a = new test();
$b =& new test();
$c =& $b;
function ta() {
 global $a,$b,$c;
 $a->set(1);
 $b =& $a;
 $c->set(2);
}
ta();
echo "$a->v,$b->v,$c->v";

[/example]

This should display 1,1,2 since $b has been set to $a, but this pointer-assigment isn't emigrated to the global $b.

I have done many expirements with it to see if i could further specify the bug... at first i thought it was destroying non-globals that got pointed too at the end of the functioncall and thus (accidently) destroying the pointers in the process, but then if i would point $a to $b and export them both, neither should be destroyed, so the reference should stay intact... it isn't.

So the only thing that remains is that function-local pointer-assigments not seem to affect my global var.
