Reported By: marcot at tabini dot ca
Status: Open
Bug Type: Zend Engine 2 problem
Operating System: Shouldn't matter
PHP Version: 5CVS-2003-03-01 (dev)
New Comment:
NO! & YES there is an error.
No: You are declaring a *new* dynamic property c in b
which hides c from a.
YES: there is a memory leak:
/usr/src/php4-HEAD/Zend/zend_language_scanner.l(1084) : Freeing
0x40998D38 (7 bytes),
script=/usr/src/php4-HEAD/tests/classes/private_members.php
I'll have a look into it

Configure:
./configure \
--with-apxs=/usr/local/apache/bin/apxs
For example:
<?
class a
{
private $c;
function __construct()
{
$this->c = "a::c";
}
}
class b
extends a
{
private $d;
function _construct()
{
$this->d = 'b::d';
}
function test()
{
echo $this->c;
}
}
$b = new b;
//echo $b->d;
$b->test();
?>
If executed, The first echo statement returns an error, as expected.
The $b->test() call, however, returns `a::c', which I think is
incorrect, as it should either not return anything or produce an error,
since a::$c is declared as private and should not be available to the b
namespace.
