Description:
------------
This is either a bug in PHP, or an undocumented consequence of the language's design -- either of which should be addressed.

If you want to have an object set an error handler to a method in itself, such that when the object passes out of scope or gets destroyed, the __destruct method is called (and previous error handler restored), you cannot do it. The __destruct method is not called until program termination.

It appears that by setting the error handler to $this->method, causes $this to become copied rather than referenced. Using Array( &$this, 'method' ) versus Array( $this, 'method' ) has no effect on the outcome -- the problem is "problem" is the same.

It's kind'a like creating a scope wormhole, I know, but the documentation doesn't say it's not allowed! :)

Reproduce code:
---------------
class TestErrorHandler
{
    public function __construct()
    {
        print "construct\n";
        set_error_handler( Array( $this, 'handler') );
    }
    public function __destruct()
    {
        print "destruct\n";
        restore_error_handler();
    }
    public function handler()
    {
        print "handled\n";
    }

}

$foo = new TestErrorHandler();
$foo = new TestErrorHandler();

print "done.\n";



Expected result:
----------------
construct
destruct
construct
done.
destruct


Actual result:
--------------
construct
construct
done.
destruct
destruct
