Log: Fixed bug #54372 (Crash accessing global object itself returned

'Fatal error: Call to a member function b() on a non-object' is wrong
behaviour either. Test should return nothing.

I can reproduce the issue using:
<?php
class test_class
{
public function __get($name)
{
return $this;
}
}
global $test3;
$test3 = new test_class();
var_dump($test3->a);
?>
Your test gives me 'Fatal error: Call to a member function b() on a
non-object'.
