Bug description: $this may be modified indirectly inside a method
Description:
------------
Trying to assign to $this inside a method results in:
"Fatal error: Cannot re-assign $this".
However, using a reference it is possible to modify $this.
Reproduce code:
---------------
class A
{
function f()
{
$p =& $this;
$p = "whatever";
var_dump($this);
// Note: accessing fields and invoking methods
// via $this still works fine.
}
};
$x = new A();
$x->f();
Expected result:
----------------
Fatal error: Cannot re-assign $this
Actual result:
--------------
string(8) "whatever"
