I'm reopening this so that we can discuss it. I don't think we should
be silently ignoring references as that's something vague. See mail to
internals@ in a bit.

So for the curious who are wondering what "fixed" means. The & is
simply ignored in this case now.

Fixed in CVS HEAD and PHP_5_1.

It has everything to do with the new object model. Take this code:
$x = &$this;
$x = 'foo';
For performance reasons we need to catch such references when they
happen in order to prevent the object being overwritten inside itself.
It would be a bit less confusing if the error happened on the actual
assignment, but in this new object model there $x = &$this; is just as
wrong as $this = &$x since the only purpose one could have for making a
reference to $this itself is if you wanted to change it directly. In
all valid cases this should be $x = $this.
I suppose an option would be to ignore the reference in this case and
continue on. That seems to be happening with that last indirect case
you posted, but it would cost us a lookup.

And why does the following code work then???
<?php
class Foo {
function Foo() {
$this->ref =& $this;
$this->ref->test();
}
function test() {
echo 'test';
}
}
$foo = new Foo();
?>
