Edit report at https://bugs.php.net/bug.php?id=78918&edit=1 ID: 78918 Comment by: brent at spatie dot be Reported by: brent at spatie dot be Summary: Segfault with preloading Laravel Status: Feedback Type: Bug Package: opcache Operating System: macOS 10.14 PHP Version: 7.4.0 Block user comment: N Private report: N New Comment: Hi Nikita It's working now with the latest 7.4 build (7.4.2-dev). That's great! I'm getting some "already declared class" warnings still, but I guess that has to do with my preload script, stuff like ": Cannot declare interface Nette\DI\Config\IAdapter, because the name is already in use in /Users/brent/dev/spatie/aggregate.stitcher.io/vendor/nette/di/src/compatibility.php" I guess this one can be closed though, thank you for looking into this :) Previous Comments: ------------------------------------------------------------------------ [2019-12-18 11:12:14] nikic@php.net Unfortunately I'm not able to reproduce the segfault on Ubuntu. To make sure we're on the same page, here's what I do: * Clone the git@github.com:brendt/aggregate.stitcher.io.git repo * Run ~/php-7.4/sapi/cli/php composer.phar install * Patch vendor/nesbot/carbon/src/Carbon/Traits/Date.php to comment out the problematic $days static property. * Run the following command: ~/php-7.4/sapi/cli/php -c ~/php-7.4/php.ini -d opcache.preload=preload.php -S localhost:8000 -t public * Open localhost:8000 in the browser Does this match what you're doing? > Using gdb I've got this (still no idea if this is useful at all for you) > > 0x00007fff7c4ec61a in ?? () from /usr/lib/system/libsystem_kernel.dylib Is this the full backtrace? Do you get anything more when typing "backtrace" into gdb? ------------------------------------------------------------------------ [2019-12-17 15:36:40] bugreports at gmail dot com > [2019-12-17 15:01 UTC] brent at spatie dot be > I've used PHP 7.4.1-dev now (commit > https://github.com/php/php-src/commit/5ddcacac) why? 7.4.1.dev is stone old when it comes to recent fixes https://git.php.net/?p=php-src.git;a=shortlog;h=refs/heads/PHP-7.4 ------------------------------------------------------------------------ [2019-12-17 15:01:17] brent at spatie dot be Hi Nikita I've used PHP 7.4.1-dev now (commit https://github.com/php/php-src/commit/5ddcacac) I'm still getting a segfault: [1] 86293 segmentation fault <php path>/bin/php -S localhost:8181 -t public Using gdb I've got this (still no idea if this is useful at all for you) 0x00007fff7c4ec61a in ??

Some of them will only make 7.4.2 (current 7.4 branch). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
