Issue: https://github.com/php/php-src/issues/12099 Author: particleflux ### Description Running phpdbg for coverage reporting results in an abort. On the following example project: [phpdbg-crash.zip](https://github.com/php/php-src/files/12490863/phpdbg-crash.zip) The command ``` phpdbg -qrr vendor/bin/phpunit ``` crashes with ``` PHPUnit 9.6.11 by Sebastian Bergmann and contributors.

Happened on PHP 8.0.30 and 8.1.21, on gentoo and on ubuntu.) ### PHP Version PHP 8.1.21 ### Operating System Gentoo (but also on ubuntu docker cimg/php:8.1 and 8.0)
