The error shown below is triggered while running the tests for PHPUnit 9.3 (master) with PHP 8.0-dev and JIT (opcache.enable=1, opcache.enable_cli=1, opcache.optimization_level=-1, opcache.jit=1205, opcache.jit_buffer_size=4096M) on Windows:

This is the GitHub Action in question:

The code in question looks like this:

656    private function addFunctionToMap($name, $startLine, $endLine): void
656    {
657        for ($line = $startLine; $line <= $endLine; $line++) {
658            $this->lineToFunctionMap[$line] = $name;
659        }
660    }

The error is not triggered with PHP 8.0-dev and JIT on Linux (or with any other PHP configuration that is tested against in PHPUnit's CI pipeline).

Is this still an issue? At least looking at your GH actions, the jit config seems to be passing.

The php-token-stream library has been abandoned and is no longer used by PHPUnit / php-code-coverage. That explains why the issue (if it were still around, which I do not know) does not show up in CI.

Ah, I missed the fact that this is a Windows only issue, so of course it doesn't reproduce for me... Can't help then.

Does anybody still experience this issue with PHP 8.0.13?
