Bug description: Segfault when using clone '$this>test2' notation in __clone
method
Description:
------------
PHP segfaults when there is code like '$this->object = clone $this>object'
in __clone method. note the '>' syntax which is faulty ofcourse but
produces the segfault.
tested with latest cvs:
PHP 5.1.3-dev (cli) (built: Feb 13 2006 10:52:02)
Reproduce code:
---------------
class test2 {}
class test {
public $test2;
public function __construct() {
$this->test2 = new test2();
}
public function __clone() {
$test2 = clone $this>test2;
}
}
$test = new test();
$test2 = clone $test;
Expected result:
----------------
Notice: Use of undefined constant test2 - assumed 'test2' in FILE on line
XX
Notice: Object of class test could not be converted to int in FILE on line
XX
Actual result:
--------------
