Bug description: memleak when creating default object caused exception
Description:
------------
Kinda hard to explain, better look at the code below.
The leak is only reproducible when return value is used, remove $var and
it's gone.
Reproduce code:
---------------
<?php
function err($errno, $errstr, $errfile, $errline)
{
throw new Exception($errstr);
}
set_error_handler("err");
class test {
function foo() {
$var = $this->blah->prop = "string";
var_dump($this->blah);
}
}
$t = new test;
try {
$t->foo();
} catch (Exception $e) {
var_dump($e->getMessage());
}
?>
Actual result:
--------------
