Description:
------------
Using the below script with JIT=1205, I'm able to trigger a segfault on require().
This does not happen if JIT is disabled.
This only happens on Windows.
Test script:
---------------
test.php:
<?php
declare(strict_types=1);
system(PHP_BINARY . " -v");
echo "Including script 'Test.php'\n";
require dirname(__DIR__) . '/helpers/Test.php';
echo "Done!\n";
helpers/Test.php:
<?php
class Test{
public static function doSomething() : void{
$time = time();
while(time() < $time + 10){}
echo "done\n";
}
}
Expected result:
----------------
PHP 8.0.7 (cli) (built: Jun 2 2021 00:40:57) ( NTS Visual C++ 2019 x64 )
Copyright (c) The PHP Group
Zend Engine v4.0.7, Copyright (c) Zend Technologies
with Zend OPcache v8.0.7, Copyright (c), by Zend Technologies
Including script 'Test.php'
Done!
Actual result:
--------------
As seen in the Windows, JIT=1205 run here: https://github.com/dktapps/php-8-jit-bugs/runs/2935629701?check_suite_focus=true
