PHP 8.1: PHPUnit\Framework\Exception: Aborted (core dumped)

[ostrolucky]

Q	A
PHPUnit version	9.x, 10.x
PHP version	8.1.0-dev (389b2a446370f8391cedd598bfd27f8120778722)

Summary

Looks like doctrine-bundle tests under PHP 8.1 usually fail. See https://github.com/doctrine/DoctrineBundle/runs/4203967904?check_suite_focus=true

Problem is sometimes gone when I rebuild the job

Possibly related: #4622

You have found a problem in the PHP runtime that leads to a segmentation fault. An issue like this has to be reported at https://bugs.php.net/report.php using a minimal, self-contained, reproducing test case.

Please note that a test case that needs to be run through PHPUnit does not qualify as either "minimal" or "self-contained" when reporting bugs for the PHP runtime. Best practices for reporting bugs in PHP are documented here.

Could be also issue in pcov, setup-php, some weird thing phpunit does and so on, like you mentioned here #4622 I am not going to do the work of creating minimal reproducer at the moment, but thought it would still be good to have a bug report about this somewhere.

Looks like it's this bug https://bugs.php.net/bug.php?id=81612 and there is a fix for it here krakjoe/pcov#75

Removing processIsolation attribute in phpunit.xml fixed it for me.
