 New Comment:

Unless we re-implement the whole alias thing, drop the tricky.

we could not fix this properly, even we can do some works in the abstrct 
methods 
copy, but it still in a wrong way.

Dmitry,  could you please look at this?

thanks

Description:
------------
This bug is related to #61998, but was spotting when I fixing the bug #62358, 
PS: 
it really tough to refine this reproduce script :)




Test script:
---------------
<?php

function __autoload($name) {
    if ($name == "B") {
        eval ("abstract class B extends A { }");
    } else if ($name == "A") {
        eval ("abstract class A { use T { T::__construct as __asconstruct; }}");
    } else if ($name == "T") {
        eval ("trait T { public function __construct() { } }");
    }
    return TRUE;
}

class C extends B {
    public function __construct() {
    }
}

Expected result:
----------------
no error

Actual result:
--------------
