[Bug libstdc++/13542] the overload of < operator doesn't work for complex<double> when use stl sort

Your op< is in the global namespace, but at the place where
    it is used (inside std::sort), only
    operators in namespace std are looked up because both operands
    are in namespace std. There are several other instances
    of this bug/feature in the database.
    
    You can work around the problem by putting the op< into
    namespace std.
