Bug #72469 [NEW]: Coredump while constructing the class in the constructor
From: brupje at gmail dot com
Operating system: Ubuntu 14.04.4 LTS
PHP version: 7.0.7
Package: Reproducible crash
Bug Type: Bug
Bug description:Coredump while constructing the class in the constructor
Description:
------------
I am using the ondrej-php compiled 7.0.7 packages on a up-to-date Ubuntu
14.04 LTS. I was doing some bad coding practises as per our current cms
when a coredump occurred. I was able to create a test script that will
reproducibly on my system will coredump apache.
The original code was much longer and more complex with subclasses, but
I was able to minimize it to the code below. Basically what I did was
put the class into a global variable and the use that global variable to
call a non-existing function. It coredumps at creating the class in
constructor.
Constructing the class you are currently constructing into a global is a
one thing that should not be allowed I think, which would fix this
particular issue at least.
Test script:
---------------
<?php
class foo {
public function __construct() {
$_GLOBAL['bar'] = new foo();
}
}
$foo = new foo();
?>
Expected result:
----------------
Error that you can't create the partial class in the constructor.
Actual result:
--------------
Coredump in apache child
