Summary0002283: SoapClient usage causes segfault with codecoverage
Description

using the soapclient like this:

    // we fake the soap client to return our prerecorded xml response and have it decoded via the SoapClient
    $client = new class ( __DIR__ . '/StationList.wsdl', ['trace' => true]) extends SoapClient {
        public function __doRequest(string $request, string $location, string $action, int $version, bool $oneWay = false): string
        {
            return \file_get_contents(__DIR__ . '/Result.xml') ?: throw new RuntimeException('missing PointListRequestResult');
        }
    };

    $client->getTheStationListFull();

will cause a segfault, see provided github repository for a small reproducer.

I can reproduce this, but I haven't managed to find out why this happens yet.

I did manage to reduce your test case to even smaller - without having to use PHPUnit at all:

$ cat test.php 
<?php
require_once __DIR__ . '/src/Foo.php';

$foo = new Foo();
?>

And running it with:

php -n -dzend_extension=xdebug -dxdebug.mode=develop test.php

Code coverage does also not need to be enabled.

just as an FYI, as of now, i found a viable workaround:

#[RunClassInSeparateProcess]

on my test does not trigger the crash shrug no idea why, but yeah

This is likely caused by a bug in PHP (https://github.com/php/php-src/pull/16252), which should get fixed in the next PHP 8.2/8.3/8.4 releases.

Can you still reproduce this with PHP 8.3.14?
