Is this the same as bug 6417?

OK, this only affects objects in the array whose methods
have been accessed. Other objects are still copies. It
also works on php-4.0.3pl1 on the Win32 platform.

A short script:
<?php
class test_class_2{
var $name;
function distort_reality(){
echo("Method Called.<br>n");
return;
}
}
$a[] = new test_class_2;
$a[0]->name = 'Original';
echo('$b = $a<br>'."n");
$b = $a;
echo("Original contains: {$a[0]->name}<br>n");
echo("Copy contains: {$b[0]->name}<br><p>n");
echo("Change contents for $b<br>n");
$b[0]->name = 'Copy';
echo("Original contains: {$a[0]->name}<br>n");
echo("Copy contains: {$b[0]->name}<br><p>n");
$a[0]->distort_reality();
echo('Once again, $b = $a<br>'."n");
$b = $a;
echo("Original contains: {$a[0]->name}<br>n");
echo("Copy contains: {$b[0]->name}<br><p>n");
echo("Change contents for $b<br>n");
$b[0]->name = 'Copy';
echo("Original contains: {$a[0]->name}<br>n");
echo("Copy contains: {$b[0]->name}<br>n");
?>
The output from the script:
$b = $a
Original contains: Original
Copy contains: Original
Change contents for $b
Original contains: Original
Copy contains: Copy
Method Called.
Once again, $b = $a
Original contains: Original
Copy contains: Original
Change contents for $b
Original contains: Copy
Copy contains: Copy
Basically, if $a is an array of objects and any method of an object is called any
subsequent copy of $a becomes linked to the original. Any change to the copy
propagates through to the original.
