It seems that your CI does not test all variants?

@ClausKlein It was very difficult to find a set of CI targets that worked consistently with conan and this set of GUI projects, so I filtered it down to one compiler per OS, to make sure all OSes were covered.

I'm happy to add another CI target back, if we can get that working and have more variants covered.

-- update

I'm unable to reproduce this with clang-tidy 13.0.1 locally.
