Hello, I was experimenting using clang-tidy (version 14) and ran into a crash.
I can't reproduce it on my machine directly, only using github actions or `act`.
I've tested both with clang 14 and GCC 12.3, I'm unsure if that is relevant for this issue though.
The backtrace is located [here](https://github.com/F0bes/gifscript/actions/runs/8494915473/job/23270632256)

You should be able to test it yourself by checking out this branch https://github.com/F0bes/gifscript/tree/broken-clang-tidy
[commit sha if/when the branch gets deleted in the future](https://github.com/F0bes/gifscript/commit/84ab0cb9caa1811f994365c69dad05a2ab0a2720) and running the github action 'branch-build'
Hope it's enough information. I couldn't provide a better reproducible sample.
