I'm wondering if it's necessary to test both in stable and nightly (lot of variations) ? Maybe only testing php8.4 + nts + nightly is enough ?

@joelwurtz unstable has pointed out some problems in the past and I would like to keep it for that reason. Maybe move it to a nightly pipeline though.

Regarding the amount of variations, we should test all supported versions.
I'd like to reduce it as well, and things like 8.0 which is EOL could reduce it a little. I personally would like to drop it but till then I don't see much of a way to reduce it.

While CI takes a little time it is still reasonable and Id rather have more than too few checks.

Would having unstable only on one version (like done actually) would be enough ? Or should we do it on all versions ?

Also don't know why it does not work on windows, i can reproduce the problem on my windows system but it's only when clang > 15 (when using clang 15 it works) but looking at the script in CI it does not seems to install clang 15 actually so i don't know why it works ?

At least for windows we need all unstable, as stable is not supported afaik. On all others I would be fine with one unstable but full test on a nightly build.

I don't have windows. So prob not much help there.

I'm closing this atm, too old, and didn't achieve what i want
