It might be related in the sense the namelookup of rank is happening a
definition time rather instantation time.

Shorter testcase (without includes):

template <int> struct rank{};

struct A{ int rank; };

template<typename T>
bool comp_rank(const T &a, const T &b){
            return a.rank < b.rank;

int main()
            A a{42}, b{0};
                comp_rank(a, b);
