Summary0002175: Crash with EXC_BAD_ACCESS in xdebug_str_create
Description

Xdebug 3.2.1 crashes within PHP 8.2.5 by opening a self developed web application (based on Symfony). This happens on arm64/mac (I saw something similar on an amd64/linux machine, however, this issue report is specifically for the trace shown below).
Depending on the developer machine this happens with the Symfony debug mode on or off. In this case it has to be disabled to trigger the crash (APP_ENV=prod).

Steps To Reproduce
  1. Start the server: SSL=1 lldb -- php -d variables_order=EGPCS -S 0.0.0.0:8196 -t web web/router.php
  2. Open the page: curl http://localhost:8196
Additional Information

% SSL=1 lldb -- php -d variables_order=EGPCS -S 0.0.0.0:8196 -t web web/router.php
(lldb) target create "php"

(lldb) settings set -- target.run-args "-d" "variables_order=EGPCS" "-S" "0.0.0.0:8196" "-t" "web" "web/router.php"
