Summary	0002108: Segfault on PHP8.1 with PHPUnit 10 when path coverage is enabled
Description	I noticed that Codeception Github Actions builds that test PHPUnit 10 started failing on 3rd of August. It happens on PHP 8.1.8 with Xdebug 3.1.2 and 3.1.4. There is no more than 20 method calls between xdebug_start_code_coverage(7) and the place of segmentation fault, so it should be easy to debug, but I haven't managed to reproduce this fault with standalone script or test project containing just a few tests, so full Codeception repository is required for reproducing this fault. Segmentation fault happens in this loop: https://github.com/Codeception/Codeception/blob/c6595a9a13d1f46b9e98e8bb190f980fc17d67ef/src/Codeception/Test/Test.php#L153-L160 `foreach ($this->hooks as $hook) { if ($hook === 'codeCoverage' && !$this->collectCodeCoverage) { continue; } if (method_exists($this, $hook . 'Start')) { $this->{$hook . 'Start'}(); } }` There are 4 items in hooks array `'ignoreIfMetadataBlocked', 'codeCoverage', 'assertionCounter', 'errorLogger'` codeCoverage hook executes `xdebug_start_code_coverage(7)` (indirectly, through php-code-coverage library) then assertionCounter hook executes `\PHPUnit\Framework\Assert::resetCount()) and segmentation fault happens on`}`after`$this->{$hook . 'Start'}();` I attached backtrace produced by gdb, but crash didn't happen when executed with valgrind: XDEBUG_MODE=coverage valgrind php codecept run tests/unit/Codeception/StepTest.php -o 'c overage: path_coverage: true' --coverage >valgrind.log 2>&1
Steps To Reproduce	git clone https://github.com/Codeception/Codeception.git -b xdebug-segfault cd Codeception composer install XDEBUG_MODE=coverage ./codecept run tests/unit/Codeception/StepTest.php -o 'coverage: path_coverage: true' --coverage

Naktibalda 2022-08-07 19:14 reporter ~0006351	Failing build sets `minimum-stability` to `dev` and installs a lot of branches. I identified that segmentation fault happens since this commit in symfony/console library https://github.com/symfony/console/commit/5b066d629a77b03ba804f4030a0f13f83665886b

derick 2022-08-09 10:02 administrator ~0006354	Hi, thanks for the small reproducible case, but when I run it, i get a PHP error: `$ XDEBUG_MODE=coverage ./codecept run tests/unit/Codeception/StepTest.php -o 'coverage: path_coverage: true' --coverage Codeception PHP Testing Framework v5.0.0 https://helpukrainewin.org [Seed] 1249552899 Fatal error: Declaration of Codeception\PHPUnit\Wrapper\Test::run(PHPUnit\Framework\TestResult $result): void must be compatible with PHPUnit\Framework\Test::run(): void in /tmp/2108/Codeception/src/PHPUnit/Wrapper/PhpUnit10/Test.php on line 10` And I don't see what I need to update to fix this. cheers, Derick

derick 2022-08-09 11:01 administrator ~0006355	OK. I have made this change: `diff --git src/PHPUnit/Wrapper/PhpUnit10/Test.php src/PHPUnit/Wrapper/PhpUnit10/Test.php index 4ee087c64..b76916f7f 100644 --- src/PHPUnit/Wrapper/PhpUnit10/Test.php +++

And when running with `USE_ZEND_ALLOC=0`, I am getting the following valgrind warnings, which can easily turn into actual crashes: $ XDEBUG_MODE=coverage valgrind php ./codecept run

Naktibalda 2022-08-13 18:25 reporter ~0006363	Priority can be changed to low, because segmentation fault no longer happens after https://github.com/symfony/console/commit/8fe565067c4e8786d10e6ba36b161fc10e4c5224

Naktibalda 2022-11-20 12:04 reporter ~0006448	symfony/console 6.2.0-BETA3 causes segmentation fault with path coverage again after: https://github.com/symfony/console/commit/01c90dba590bcdc5699597b8090407b4441dfad4

Naktibalda 2022-11-20 18:24 reporter ~0006449	I failed to reproduce this segfault without Codeception, here is the smallest reproduction I can make: https://github.com/Naktibalda/codeception-segfault I noticed that segfault doesn't happen if foreach in linked symfony/console code is removed ($commandSignals is empty, removing code inside loop makes no difference).

Naktibalda 2022-12-02 20:40 reporter ~0006457	This segmentation fault was released as symfony/console 5.4.16, 6.0.16, 6.1.8 and 6.2.0 It affects Codeception 5 when used with PHPUnit 9.5 too. Let's wait and see if anyone uses path coverage with Codeception 5.

derick 2022-12-05 11:34 administrator ~0006459	I can reproduce this with your minimal codeception case. Going to see why now though :-)

derick 2022-12-05 18:23 administrator ~0006460 Last edited: 2022-12-05 18:39	I have made this PR, which address both your initial reproduce case, as well as your minimal one: https://github.com/xdebug/xdebug/pull/873 Would you be able to test with this branch? It's https://github.com/derickr/xdebug/tree/issue2108-cc-segfault cheers, Derick

Naktibalda 2022-12-08 18:12 reporter ~0006465	Testing Xdebug looks complicated, it would be nice if you had step-by-step instructions how to do it. Ot looks like compiled xdebug is unlikely to collaborate with installed php on Ubuntu 22.04, am I wrong about it? I could try to reuse your CircleCI script to build a docker image, but it is time consuming and I have nothing substantially different from what you already tested to test, so most likely I won't test it. Please merge your pull request if it looks good to you.

derick 2022-12-08 18:44 administrator ~0006466	Testing is covered in the README: https://github.com/xdebug/xdebug#testing But I meant more, compile the Xdebug branch that I pointed to, and then run your tests :-) In any case, I have merged it (through https://github.com/xdebug/xdebug/pull/873), and it will be part of the 3.2.0 release, that I will be making straight away.

Naktibalda 2022-12-10 18:32 reporter ~0006472	Thank you, I can confirm that Xdebug 3.2.0 no longer causes this segmentation fault.
