Bug Type: Bug
Bug description:get_defined_constants() causes PHP to crash in a very limited
case.
Description:
------------
The function get_defined_constants(); (with or without the bool parameter)
causes
PHP to segfault when used in the same script as a Class that uses a Trait
which
has the __CLASS__ magic constant somewhere in it.
If you replace __CLASS__ with get_called_class() it works fine.
Test script:
---------------
<?php
trait TestTrait
{
public static function testStaticFunction()
{
return __CLASS__;
}
}
class Tester
{
use TestTrait;
}
$tester = Tester::testStaticFunction();
get_defined_constants();
echo "It Worked!";
Expected result:
----------------
The text "It Worked!" output.
Actual result:
--------------
PHP crashes and the following is left in my Apache error log:
[Thu Jul 18 13:22:33 2013] [notice] child pid ##### exit signal
Segmentation fault
(11)
