integer overflow in spl

[chongwick]

Description

The following code:

<?php
$v_19798 = 0;
$v_19822 = curl_init();
$v_19835 = curl_exec($v_19822,);
$v_19802 = 2;
$v_19804 = 3;
$v_19806 = 4;
$v_19808 = 5;
$v_19796 = array('zero' => $v_19798,'one' => $v_19835,'two' => $v_19802,'three' => $v_19804,'four' => $v_19806,'five' => $v_19808,);
try{
$v_19796 = array('zero' => $v_19798,'one' => $v_19835,'two' => $v_19802,'three' => $v_19804,'four' => $v_19806,'five' => $v_19808,);
$v_19811 = new ArrayIterator($v_19796,);
$v_19823 = ob_start();
$v_19813 = PHP_INT_MAX;
$v_19814 = new LimitIterator($v_19811,$v_19823,$v_19813,);
foreach ($v_19814 as $v){
$v_19816 = $v;
}
$v_19815 = $v;
}
catch (OutOfBoundsException $e){
$v_19809 = $e->getMessage();
$v_19810 = '\n';
}

Resulted in this output:

/nightly_php/php-src/ext/spl/spl_iterators.c:2121:83: runtime error: signed integer overflow: 1 + 9223372036854775807 cannot be represented in type 'long'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior /nightly_php/php-src/ext/spl/spl_iterators.c:2121:83

But I expected this output instead:

PHP Version

nightly

Operating System

20.04
