Summary0001992: Code Coverage with filter produces Segmentation fault on xdebug_stop_code_coverage()
Description

Xdebug throws a Segmentation fault when xdebug_stop_code_coverage() is called, but nothing was covered.
I tracked it down to the call to this function while debugging the PhpUnit test.

php -v
PHP 7.4.21 (cli) (built: Jul  1 2021 19:30:38) ( NTS )
Copyright (c) The PHP Group

    with Zend OPcache v7.4.21, Copyright (c), by Zend Technologies
    with Xdebug v3.0.4, Copyright (c) 2002-2021, by Derick Rethans
Steps To Reproduce
  • extract attached file
  • composer install
  • ./vendor/bin/phpunit --prepend xdebug-filter.php
  • See segmentation fault happening: 
    
./vendor/bin/phpunit --prepend xdebug-filter.php --debug
PHPUnit 9.5.6 by Sebastian Bergmann and contributors.

Test 'Foo\Tests\BarTest::testNothing' started
Segmentation fault

Additional Information

The segfault also occured in php 7.4.20, Xdebug 3.0.2 and also with PHPUnit 7.5.20 (with appropriate phpunit.xml).

I ran the tests in a php docker container based on buster.

TagsNo tags attached.

I can reproduce this, and much easier as well:

derick@gargleblaster:/tmp/1992$ cat test.php
<?php
xdebug_start_code_coverage();
xdebug_stop_code_coverage(true);

derick@gargleblaster:/tmp/1992$ cat filter.php
<?php
xdebug_set_filter(XDEBUG_FILTER_CODE_COVERAGE, XDEBUG_PATH_INCLUDE, ['src/']);

derick@gargleblaster:/tmp/1992$ php -dxdebug.mode=coverage -dauto_prepend_file=filter.php test.php
Segmentation fault
