That would be > legitimate, I'm just curious. If there is another translation unit in the *same* binary that defines struct s1, then yes, it's "stolen", as you say. But if in the entire binary, struct s1 is just declared (not defined), then it'll compare equal to any struct s1 that is defined in the *second* binary.
