Bug description:Segfault with strange __destruct() for static class variables
Description:
------------
When a static class variable is assigned a nested destructable object, it
behaves differently when assigned before or after the instantiation an
object of the class to which the static property belongs.
When the variable is assigned after object instantiation, the process
segfaults.
(tested: PHP 5.3.1 behaves correctly)
Test script:
---------------
<?php
class DestructableObject
{
public function __destruct()
{
}
}
class DestructorCreator
{
public function __destruct()
{
$this->test = new DestructableObject;
}
}
class Test
{
public static $mystatic;
}
// Uncomment this to avoid segfault
//Test::$mystatic = new DestructorCreator();
$x = new Test();
if (!isset(Test::$mystatic))
Test::$mystatic = new DestructorCreator();
echo 'bla';
Expected result:
----------------
bla
Actual result:
--------------
Segfault
