Crash with property declaration in class derived from V8Js class

[stesie]

The following code runs as expected in PHP 5.3.3 but crashes PHP 5.4.4

<?php

class V8Wrapper extends V8Js {
    public $testing;  // remove line to make it work :-)

    public function __construct() {
        parent::__construct();
        $this->testing = 23;
    }
}

$v8 = new V8Wrapper();
$v8->executeString("print('foo');");

If the public $testing; property declaration is removed from the code everything works well, even with PHP 5.4.4

I probably will have a go to fix this, but do we want to fix this, or do you consider it expected behaviour? (after all it shouldn't crash no matter what)

cheers stesie

I'd try to fix it.
