Bug description:segfault when __toString() returns "$this"
Description:
------------
Hi,
Casting $this as string inside __toString() magic function makes php crash.
It
seems it ran into an infinite loop.
Tested on PHP 5.5 and 5.4.11, even 5.3.6
Test script:
---------------
class base {
function __toString() {
return "$this";
}
}
echo new base();
Expected result:
----------------
Exception thrown, or an error message.
Actual result:
--------------
Violación de segmento (`core' generado)
[Segmentation Fault ('core' dumped)]
