Sorry, I just realized the bug has already been fixed in the current PHP-8.0 branch.

Description:
------------
PHP 8.0.4RC1 (cli) ( NTS DEBUG ) crashes when running the test script with function JIT enabled.

I also tested with PHP 8.1.0-dev (master-Git-2021-03-29) which does not seem to have this bug. It
shows the expected result.

Configure Command
=================
./configure --prefix=/dev/shm/test/php-8.0.4RC1 --disable-all --enable-debug --enable-opcache
--enable-opcache-jit

Command
=======
php -d zend_extension=opcache -d opcache.enable_cli=on -d opcache.jit_buffer_size=64M -d
opcache.jit=function test.php


Test script:
---------------
<?php

class Test
{
    public $test = null;

    function test()
    {
        var_dump($this->test . number_format(0));
    }
}

(new Test())->test();


Expected result:
----------------
STDOUT
======
string(1) "0"


Actual result:
--------------
STDERR
======
php: /dev/shm/test/php-src/Zend/zend_variables.c:65: zend_string_destroy: Assertion
`zend_gc_refcount(&(str)->gc) == 0' failed.
