[Bug]: DD Trace breaks project with PHP 8.3.7 - Laravel 11.7

[rdizio]

Bug report

Hi, I was testing the new Laravel 11 with Datadog APM & PHP 8.3 and it's breaking when returning a New Illuminate\Http\JsonResponse object. This only happens when I enable the APM.

Step to reproduce:

1- Enable the DD Trace 1.0.-beta with php 8.3.7
2-Use Laravel 11.7
3-From php artisan tinker. Create a new model object and try to pass it to the Illuminate\Http\JsonResponse class:

This error occurs after adding DD trace php module to my php container. As soon as I delete the DD trace module, Illuminate\Http\JsonResponse works just fine.

PHP version

8.3.7

Hey @rdizio 👋

I've been trying to reproduce it (on Tinker or web requests), but I haven't been able to exhibit your behavior. Would you be able to provide a reproducer (e.g., a sample docker app) for the erroneous behavior?

Thanks!

[rdizio]

Hi @PROFeNoM,

Yes, it seems like the behavior is not consistent for me. I ran new JsonResponse($user); and I only get the error after the 3er or second attempt. I don't know if this has anything to do with opcache or JIT:

[rdizio]

@PROFeNoM let me know if you are able to replicate the issue. I'm can also send a docker demo app

[PROFeNoM]

Hi @rdizio,

Sorry for the delay. These last few days, I have had many things on my plate and didn't have enough time.

As can be seen in the (shortened) output below, even with JiT enabled, it doesn't seem like I can replicate the behavior (in PHP 8.1, 8.2, and 8.3).

If you can provide us with a docker demo app, then that's obviously ideal for us as that would streamline the investigation 😃 Otherwise, it may be interesting to first:

• Enable the debug logs (I really don't expect anything, but it's always worth a try 🤷)
• Disable JiT to see if the behavior persists. If this is JiT-related, a sample reproducer is even more essential, as the engine may have a particular loophole.
• Find out where this str_pad call happens

Thanks for your assistance
