[Bug]: Segmentation fault on PHP 8.4.4 (uncaught exception; Symfony application [env=prod;debug=false]; preload enabled)

[lcobucci]

Bug report

I'm having segfaults on both php -S and php-fpm when having uncaught exceptions (e.g. Symfony\Component\HttpKernel\Exception\NotFoundHttpException) on a Symfony application with opcache preload enabled.

Not sure if this is coming for ddtrace or PHP, but everything works if I completely disable the extension (removing the ddtrace.ini file) or disable opcache preload. The flows that don't have uncaught exceptions also work fine with ddtrace and opcache preload enabled.

Here's the backtrace of the segfault (php -S ...):

Upgrading from

Upgrading from PHP 8.3.17 and ddtrace 1.6.3

[bwoebi]

I've recently seen php/php-src#17715, maybe it's related to that. I have on my todo list to fix that issue soon. We might have to also add a workaround for the early 8.4 versions.
There exist codepaths using enums in Symfony...

[lcobucci]

Thanks @bwoebi!

We're taking this upgrade process slowly and making everything works before rolling php 8.4 to all applications.

Let me know if you need a hand testing this out 👍

[bwoebi]

@lcobucci I have a workaround for the PHP 8.4 version regarding enums here: https://output.circle-artifacts.com/output/job/d6bf44f4-6095-4889-bbf7-8c4c078b4e57/artifacts/0/datadog-setup.php
Please let me know if this fixes it, or if there's any other issue, then I'll have to dig in!

[lcobucci]

@bwoebi that did the trick, no more segfaults on the scenario I reported 👍

Thank you!
