Bug description:Undocumented BC break with changing __construct() signature
Description:
------------
PHP 5.* allows changing an abstract __construct() signature without any
notice. PHP 5.4 issues fatal error.
I didn't find this BC break in news.txt so I think that it is a bug.
Test script:
---------------
<?php
abstract class P {
abstract function __construct();
}
class C extends P {
function __construct($a) {
}
}
?>
Expected result:
----------------
Nothing - same as in PHP 5.*.
The strange thing is that if we replace "abstract function __construct();"
by "function __construct() {}" then the behavior is same as in previous
versions.
Actual result:
--------------
Fatal error: Declaration of C::__construct() must be compatible with that
of P::__construct()
