Bug description: Circular call leeds to segmentation fault

Description:
------------
Recursively calling two functions in a class leads to a segmentation
fault.

Reproduce code:
---------------
class SegFault {

public function call(){
$this->back();
}

public function back(){
$this->call();
}
}
$seg = new SegFault();
$seg->Call();


Expected result:
----------------
I'd expect some kind of error when php runs out of buffer for the
callstack - this function clearly is an example of bad code in the script
- however php shouldnt die by segmentation fault.


Actual result:
--------------
Segmentation fault
