Description:
------------
PHP CLI (console mode) crashes when executing:

var_dump(120 xor 111); //or any other number

reproducible: always


//this works fine
$ch = 120 xor 111;
var_dump($ch);

//this works too
var_dump(120);
var_dump(120 + 3);


weird because other numerical expressions do not cause the crash, only xor.

Reproduce code:
---------------
1) make test.php
2) put <?php var_dump(120 xor 111); ?> into the file
3) php test.php

Expected result:
----------------
int(120)

This is clearly 'xor' problem, since this cause crash too:

$ch = (1 xor 3);
var_dump($ch);

//this not
$ch = 1 xor 3;
var_dump($ch); //result will be 1, expecting 2
