Description:
------------
Segmentation fault on self recursive call by a class instance method to itself.

Test script:
---------------
<?php

class ABC {
    public function self_recursive() {
        $this->self_recursive();
    }
}

$obj = new ABC();
$obj->self_recursive();



Expected result:
----------------
- Memory exhausted error
- or, Max execution limit reached
- or,  a infinite recursion exception

Actual result:
--------------
Starting program: /usr/local/bin/php test.php

Program received signal SIGSEGV, Segmentation fault.
0x00000000008d51b3 in ZEND_DO_FCALL_SPEC_HANDLER (execute_data=0x7fffe3c710d0) at
/usr/local/src/php-7.0.8/Zend/zend_vm_execute.h:800
800                                     zend_execute_ex(call);
