@laund @bjorn3 @tamme After some searching, it seems that this is a bug with NixOS and Rust: rustc overrides locale to LC_ALL=C, but this changes the behavior of printf %q used by the cc wrapper on NixOS so that it encodes non-ASCII characters in octal, which clang does not understand. https://github.com/NixOS/nixpkgs/issues/419771

@HenrikLievonen @laund @tamme Maybe having rustc set LC_MESSAGES=C instead of LC_ALL=C would work?
