Is this still a issue? This report is updated a year ago...
If this report is outstanding, PHP Version is better to be updated...

assigned to zeev, as discussed we either need
a) a permanent fix
b) a permanent deep copy function and understand this effect
as a feature and users will eventually have to use deep
copies for some containers

This code is pretty self-explanatory...
Uncommenting the noticed (*[0]) line, causes the object contained ('root') in the instance
of 'obj' to be referenced to whatever, function test() uses a copy $o_copy but
reference-counting fails and the contained object 'root' is somehow referenced to the
original object in the global scope.
After having uncommented *[0] try to uncomment *[1] what should break the reference again, that made
me assuming this all is caused by reference counting...
<?php
class obj {
function method() {}
}
function test($o_copy) {
//$o_copy->root=&$o_copy->root; // *[1]
$o_copy->root->set_in_copied_o=TRUE;
var_dump($o_copy);?><BR><?php }
$o->root=new obj();
//$o->root->method(); // *[0] uncomment this line and weirdness starts
var_dump($o);?><BR><?php
test($o);
var_dump($o);
?>
