Github CI fails because of panic in autocxx-bindgen

[xxshady]

Describe the bug

autocxx-bindgen panics while bulding c++ code in github action, ~~it's not related to incompatible Clang/LLVM version since it gets updated to 16.0.6 manually~~

Panicked github action: https://github.com/xxshady/autocxx-repro/actions/runs/6064661756/job/16453314009

Full panic:

To Reproduce

https://github.com/xxshady/autocxx-repro

Expected behavior No panic

[xxshady]

seems like its related to c++20: https://github.com/xxshady/autocxx-repro/actions/runs/6292598553/job/17082160466

however, it was working completely fine with c++20 for some time before visual studio and clang were updated in windows-2022 github image

[xxshady]

Removing LLVM from PATH helps with avoiding this issue: https://github.com/xxshady/autocxx-repro/actions/runs/6380197303/job/17314131098

  set PATH=%PATH:C:\Program Files\LLVM\bin;=%
  echo %PATH%
  cargo build

Thanks for looking into this. I'm unable to eke out time to look into it right now, but my guess is that corresponding changes have been made to bindgen and need to be rolled into autocxx_bindgen.

[xxshady]

for some reason now latest version (clang --version showed clang version 18.1.3) LLVM/clang freezes compilation on windows: https://github.com/xxshady/altv-rust/actions/runs/8819720686/job/24211619136#step:9:957

~~it compiles fine on 16.0.6: https://github.com/xxshady/altv-rust/actions/runs/8818604846/job/24207787321#step:5:5~~

[xxshady]

freezes somewhere inside the autocxx_build::Builder::build method

[xxshady]

doesn't work with 16.0.6, but works with 17.0.1 https://github.com/xxshady/altv-rust/blob/740c3ca7d2ebb6fe25228d7462092ae2695d2a27/.github/workflows/test.yml#L58-L63
