This works with Clang-17, Clang-18, and clang-tidy-18. It fails with clang-tidy-17. Clang-tidy tests that directly use the `std` module work. When importing `std` clang-tidy complains about a corrupt AST in the `std` module. So this sounds like a clang-tidy-17 but that has been fixed in clang-tidy-18.
