@tibor.pacalat , seem @gabrieljenik already start to work on this. Why not assign it to Gabriel ?

Where do you see this? If you mean general ticket, then the answer is, I tried to split the sub-tickets between you two.

See https://github.com/PHPCompatibility/PHPCompatibility/issues/796

So you mean this has nothing to be updated?

Unsure , …

But i don't see why it can broke something here : https://github.com/LimeSurvey/LimeSurvey/blob/89a3800356a2e94cfb459f0a595cb382f4adb3e8/vendor/pear/pear-core-minimal/src/PEAR.php#L888

See the error log :

898 | ERROR | Since PHP 7.0, functions inspecting arguments, like debug_backtrace(), no longer report the original value as passed to a parameter, but will instead provide the current value. The
| | parameter "$mode" was changed on line 888.

We don't really care of $mode in traceback here.

(I prefer 2 eyes to set it as not needed/false positive)

I think we can live with the new output backtrace() provides.
So, yes, false postive for me. More like a warning than an error

Ok, should I close this one?

I think you can close it. If we found an issue when testing, we will re open it.
