opcache.jit=1211 in php.ini causes apache to crash

Description

I tried to configure JIT with opcache.jit=1211 in php.ini and although I could successfully do a CLI php -i, when trying to load a php webpage through apache caused apache to crash.

Commenting this out (and falling back to opcache.jit=tracing made JIT work.

PHP Version

8.1.7

Operating System

Windows 10 / Apache 2.4.54

I cannot reproduce this with php-8.1.7-Win32-vs16-x64. A stack backtrace might be helpful to figure out the root cause of the crash. Also any more relevant details about which script/application you are running (ideally a minimal reproduce script).

Here in my php.ini. You will see where I have commented out opcache.jit=1211.

I don't get a crash running php from the command line, only from Apache. Uncommenting this one line causes a crash.

P.S. Sorry - but the running a stack-trace is too much effort.

Okay, I still cannot reproduce with a similar php.ini. Does it crash if you disable Xdebug (don't load it at all)?

Hmmm. I tried this twice with both ;zend_extension=xdebug commented out and opcache.jit=1211 not commented out - one time it crashed the next time it worked.
