Bug #81298 [NEW]: Core dump on PHP 8.1

From: alec Operating system: Linux PHP version: 8.1Git-2021-07-26 (Git) Package: Reproducible crash Bug Type: Bug Bug description:Core dump on PHP 8.1 Description: ------------ Sorry for incomplete information. I hope someone could help me to find out more about this issue. For https://github.com/roundcube/roundcubemail I just enabled Github Actions tests on PHP 8.1 and I got a core dump. I'm not sure this is Github or PHP's segfault. I do not have a local PHP 8.1 installation to test with yet, so maybe someone would like to run the tests locally to verify. Here's the raw log from the GA run: https://pipelines.actions.githubusercontent.com/u0loR6uBKIBHqKHhv0hTP4yFrcdLnLzpWEg6qJMnMYCKI8ovYJ/_apis/pipelines/1/runs/418/signedlogcontent/6?urlExpires=2021-07-26T09%3A11%3A08.4028855Z&urlSigningMethod=HMACV1&urlSignature=jdCF19d3rUDCj%2FFF66ORYaUssVkTBh1vJpkIe3ey1yY%3D -- Edit bug report at https://bugs.php.net/bug.php?id=81298&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=81298&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=81298&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=81298&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=81298&r=needscript Try newer version: https://bugs.php.net/fix.php?id=81298&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=81298&r=support Expected behavior: https://bugs.php.net/fix.php?id=81298&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=81298&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=81298&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=81298&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=81298&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=81298&r=dst IIS Stability: https://bugs.php.net/fix.php?id=81298&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=81298&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=81298&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=81298&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=81298&r=mysqlcfg
