Description:
------------
[sorry for my english]
the code below cause a segmentation fault in apache 2
i try to use a parent variable in the catch statement of the second child
if i use the same variable in the first child it's seems to work
Reproduce code:
---------------
class A {
public $myVar = "";
function __construct() {
try {
$this->test();
}
catch(Exception $e) {
throw $e;
}
}
public function test() {
$this->myVar = "something<br>";
if(0!=1) throw new Exception("ERROR",100);
}
}
class B extends A {
function __construct() {
try {
parent::__construct();
}
catch(Exception $e) {
throw $e;
}
}
}
class C extends B {
function __construct() {
try {
parent::__construct();
}
catch(Exception $e) {
echo $this->myVar;
throw $e;
}
}
}
try {
$c = new C();
}
catch(Exception $e) {
echo $e->getMessage();
}
Expected result:
----------------
printing of:
something
ERROR
Actual result:
--------------
