This is a stripped-down example from a larger code-base. `object_t` represents a union, with `.outer` being one of the possible variants. Some extra notes:

- If a trailing comma is attached to `.z`, no failure occurs,  but `.y` will be de-dented heavily
- If `.w` is removed, no error occurs
- If a space between `//` and `lint` is added, no error occurs
- If the comment is removed, no error occurs
- If the `.outer` declaration is removed, no error occurs
- If `AlignArrayOfStructures` is removed, no error occurs
