Description:
------------
I´m testing some values with opcache.jit and i think exists a bug.

I commented Bug #79854 but, i think is closed and no one answers, and i can´t re-open (who can reopen, only author?)

So, i tested some values like 1255, and 1234 and i see apache resarting with some scripts.

I'm using:
- windows 10 (64 bits).
- PHP Version 8.0.0-dev (Build date: Oct 22 2020 23:41:25).
(https://github.com/shivammathur/php-builder-windows)

Test script:
---------------
1º - in php.ini --> opcache.jit = 1255
2º - start apache --> ok
3º - open link: http://localhost/dashboard/phpinfo.php --> ok
4º - open link: http://localhost/phpmyadmin --> apache crashes --> apache restart and link not open.
5º - refresh browser --> apache crashes --> apache restart and link not open.

It would be helpful if you provide a stack backtrace[1] of the
crash.

After following the steps to generate a backtrace, without a compiler on windows, I got the results ... They are a little different from the screenshot on the instructions page to do the backtrace.

I will try to send some information that I think is important ... if necessary I am willing to send debug files via email.


RESULTS when trying open phpmyadmin with opcache.jit=1255:

Possibly this is the same issue as fixed by https://github.com/php/php-src/commit/ef77d3c89f3ca7750b78a7974ebb82d8b116506f.
