Summary0001957: Xdebug and JIT seem incompatible
Description

Hi Derick,

I get this non-blocking error message :
[20-Mar-2021 08:12:17 UTC] PHP Warning: JIT is incompatible with third party extensions that override zend_execute_ex(). JIT disabled. in Unknown on line 0

As (according to php -m) the only Zend modules are
[Zend Modules]
Xdebug
Zend OPcache

I guess that the module involved is php_xdebug-3.0.3-8.0-vs16-x86_64.dll.

Thanks and regards

Vincent Tap

That is correct. You can't use PHP 8's JIT engine (as implemented in Opcache) with Xdebug. The JIT engine changes the way how PHP works in an incompatible (and un-fixable) way with Xdebug. I've made this clearer in the documentation now: https://xdebug.org/docs/compat#compat
