So, in that case, I think I would need to be able to instruct the PHP JIT engine to be turned off. Perhaps through an API? Similarly, I think it might be useful for OPcache as well, as I am getting more people confused why some breakpoints don't work, or variables don't exist: https://bugs.xdebug.org/view.php?id=1609 cheers, Derick -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
