From:             web001 at zeroj dot net
Operating system: OS X 10.10.1
PHP version:      7.0.1
Package:          SPL related
Bug Type:         Bug
Bug description:Autoload function registered by another not activated immediately

Description:
------------
See test script. An autoload function was added to autoload queue in
another autoload function. But the "child" autoload function was not
called after other functions.
It works on 5.5 and 5.6.

Test script:
---------------
<?php
spl_autoload_register(function($name){
    if($name == 'C') {
        spl_autoload_register(function($name){
            if($name == 'C') {
                class C {
                    function __construct(){
                        echo "I'm C.\n";
                    }
                }
            }
        });
    }
});

$c = new C();


Expected result:
----------------
I'm C.

Actual result:
--------------
PHP Fatal error:  Uncaught Error: Class 'C' not found
