Bug #80290 [NEW]: SegV on assert with phpunit

From: dev at mabe dot berlin Operating system: alpine:3.12 PHP version: 8.0.0RC2 Package: Reproducible crash Bug Type: Bug Bug description:SegV on assert with phpunit Description: ------------ I'm using assertions and a workaround for PHP < 7 to throw AssertionError. The code needs to work with PHP 5.6 to latest. Now with the latest PHP-8.0-rc2 I get a segmentation fault on running the tests. I have reduced the code to bare minimum but I wasn't able to reproduce the segv without phpunit. I guess it happens somewhere in a phpunit shutdown function but the seg-vault is still related to this test code - that's why I report it here. PHPUnit 9.4.1 PS: I was using a docker container running on Mac - not sure if this makes any difference. Test script: --------------- // phpunit.xml: <?xml version="1.0"?> <phpunit bootstrap="./bootstrap.php"> </phpunit> // bootstrap.php <?php // AssertionError has been added in PHP-7.0 if (!class_exists('AssertionError')) { class AssertionError extends Exception {}; } assert_options(ASSERT_CALLBACK, function($file, $line, $code) { throw new AssertionError("assert(): Assertion '{$code}' failed in {$file} on line {$line}"); }); class AssertRunner { final public static function runAssert() { assert( false, 'Message with static::class: ' . static::class ); } } function foo() { try { AssertRunner::runAssert(); } catch (AssertionError $e) { echo $e; } } foo(); // execute php -d 'zend.assertions=1' ./vendor/bin/phpunit Expected result: ---------------- No crash Actual result: -------------- AssertionError: assert(): Assertion '' failed in /workdir/bootstrap.php on line 17 in /workdir/bootstrap.php:8 Stack trace: #0 [internal function]: PHPUnit\Util\FileLoader::{closure}('/workdir/bootst...', 17, NULL, 'Message with st...') #1 /workdir/bootstrap.php(17): assert(false, 'Message with st...') #2 /workdir/bootstrap.php(25): AssertRunner::runAssert() #3 /workdir/bootstrap.php(31): foo() #4 /workdir/vendor/phpunit/phpunit/src/Util/FileLoader.php(61): include_once('/workdir/bootst...') #5 /workdir/vendor/phpunit/phpunit/src/Util/FileLoader.php(49): PHPUnit\Util\FileLoader::load('/workdir/bootst...') #6 /workdir/vendor/phpunit/phpunit/src/TextUI/Command.php(546): PHPUnit\Util\FileLoader::checkAndLoad('/workdir/./boot...') #7 /workdir/vendor/phpunit/phpunit/src/TextUI/Command.php(349): PHPUnit\TextUI\Command->handleBootstrap('/workdir/./boot...') #8 /workdir/vendor/phpunit/phpunit/src/TextUI/Command.php(116): PHPUnit\TextUI\Command->handleArguments(Array) #9 /workdir/vendor/phpunit/phpunit/src/TextUI/Command.php(101): PHPUnit\TextUI\Command->run(Array, true) #10 /workdir/vendor/phpunit/phpunit/phpunit(61): PHPUnit\TextUI\Command::main() #11 {main} Next AssertionError: Message with static::class: AssertRunner in /workdir/bootstrap.php:17 Stack trace: #0 /workdir/bootstrap.php(17): assert(false, 'Message with st...') #1 /workdir/bootstrap.php(25): AssertRunner::runAssert() #2 /workdir/bootstrap.php(31): foo() #3 /workdir/vendor/phpunit/phpunit/src/Util/FileLoader.php(61): include_once('/workdir/bootst...') #4 /workdir/vendor/phpunit/phpunit/src/Util/FileLoader.php(49): PHPUnit\Util\FileLoader::load('/workdir/bootst...') #5 /workdir/vendor/phpunit/phpunit/src/TextUI/Command.php(546): PHPUnit\Util\FileLoader::checkAndLoad('/workdir/./boot...') #6 /workdir/vendor/phpunit/phpunit/src/TextUI/Command.php(349): PHPUnit\TextUI\Command->handleBootstrap('/workdir/./boot...') #7 /workdir/vendor/phpunit/phpunit/src/TextUI/Command.php(116): PHPUnit\TextUI\Command->handleArguments(Array) #8 /workdir/vendor/phpunit/phpunit/src/TextUI/Command.php(101): PHPUnit\TextUI\Command->run(Array, true) #9 /workdir/vendor/phpunit/phpunit/phpunit(61): PHPUnit\TextUI\Command::main() #10 {main}Segmentation fault (core dumped) (gdb) bt #0 0x000055a3aa1652e9 in ??
