Previous Comments: ------------------------------------------------------------------------ [2019-12-16 09:12:39] nikic@php.net I should probably clarify that 7.4.1 will not contain all the preloading fixes. Some of them will only make 7.4.2 (current 7.4 branch). ------------------------------------------------------------------------ [2019-12-16 09:07:08] nikic@php.net @brent: Can you please check whether it works with the built-in web server? ------------------------------------------------------------------------ [2019-12-16 09:05:26] brent at spatie dot be Hi Nikita I just used 7.4.1-RC1 to try out these changes. I didn't look too hard into the Carbon issue for now, and simply removed the constant references in the vendor folder, so that I'd be able to do my tests. Unfortunately there's still a segfault, the same one: 0x00007fff7c4eb78e in ?? () from /usr/lib/system/libsystem_kernel.dylib php-fpm is able to start and preload files, it's only after sending a request that the and when the Laravel kernel is triggered that the segfault happens. When opcache.preload is disabled in php.ini, things just work fine. Let me know if there's anything else I can test. ------------------------------------------------------------------------ [2019-12-11 09:34:13] nikic@php.net The additional class_alias issue is fixed by https://github.com/php/php-src/commit/3280209c0312df000d558e029aa4e8c63912967a. ------------------------------------------------------------------------ [2019-12-11 08:02:08] nikic@php.net Additional failure case in class alias support: interface I {} class B implements I {} class_alias('B', 'C'); update_parent_ce does not handle duplicate classes correctly. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
