SoapClient Memory Leak

[chongwick]

Description

The following code:

<?php
$v_67388 = xmlwriter_open_memory();
$v_67389 = TRUE;
$v_67390 = xmlwriter_set_indent($v_67388,$v_67389,);
$v_67391 = '   ';
$v_67392 = xmlwriter_set_indent_string($v_67388,$v_67391,);
$v_67393 = '1.0';
$v_67394 = 'UTF-8';
$v_67395 = xmlwriter_start_document($v_67388,$v_67393,$v_67394,);
$v_67396 = 'root';
$v_67397 = xmlwriter_start_element($v_67388,$v_67396,);
$v_67493 = __DIR__;
$v_67494 = '/round4_groupI_xsd.wsdl';
$v_67495 = $v_67493 . $v_67494;
$v_67498 = 1;
$v_67500 = 0;
$v_67496 = array('trace' => $v_67498,'exceptions' => $v_67500,);
$v_67501 = new SoapClient($v_67495,$v_67496,);$v_67506 = $v_67501->__getlastrequest();

Resulted in this output:

SUMMARY: AddressSanitizer: 8692 byte(s) leaked in 17 allocation(s).

But I expected this output instead:

PHP Version

nightly

Operating System

ubuntu 22.04

maybe related to/a duplicate of #14044?
