I get almost the same result using php5-200304171330, on Red Hat 8.0.
The main difference is mine seg faults when trying to use __clone
<?php
class a
{
function __construct($n)
{
$this->name = $n;
}
function __clone()
{
print "cloning...\n";
$this->name = "test".$that->name;
}
}
$x = New a("tito");
$y1 = $x;
$y2 = $x->__clone();
print "test1 {$y1->name}\n";
print "test2 {$y2->name}\n";
?>
[Output]
(towely) superunknown# /php5/bin/php -q clone.php
cloning...
Segmentation fault
