Simplexml parsing with PHP 8.2 and Apache and attribute leads to an segfault

[HLeithner]

Trying to debug a simplexml object which has an attribute leads to an segfault of php 8.2 SAPI client in apache.
It works for CLI...

Example Script:

<?php

require_once __DIR__ . '/kint.phar';

$xml = <<<XML
<form name="test"></form>
XML;

$simplexml = simplexml_load_string($xml);

kint::dump($simplexml);

Workaround:
adding a type cast to string for the value solves the problem but of course this not the reason for the problem
https://github.com/kint-php/kint/blob/master/src/Parser/SimpleXMLElementPlugin.php#L102

Sadly I wasn't able to debug this in deep.

My immediate thought is that this must be a bug in mod-php since the entire thing down to HTML output works in CLI (and the server should never be segfaulting)

I'll debug this a bit further and see if I can't submit a bug report. Thanks!

It has stopped working in CLI now, so I presume whatever patch caused it either got worse or wasn't up to date in the CLI package in debian sid.

I've managed to narrow it down to this:

<?php
require 'autoload.php';

$xml = <<<XML
<form name="test"></form>
XML;

$simplexml = simplexml_load_string($xml);

var_dump($simplexml['name']);
$reflector = new ReflectionObject($simplexml['name']);
$rprops = $reflector->getProperties();

Strangely, without the composer autoloader it works fine

Edit: Bug report submitted upstream: php/php-src#10983

I'm going to close this now since it's not a kint bug. Watch that issue for more info

thanks for your engagement, so it should be fixed with php/php-src#10984
