It seems internal boost::pfr fails to deduce the type. This kind of error can usually be fixed by declaring EOSLIB_SERIALIZE() macro manually.

    TABLE messages {
      name    user;
      eosio::signed_int  i32;
      eosio::unsigned_int ui32;
      auto primary_key() const { return user.value; }
      EOSLIB_SERIALIZE(messages, (user)(i32)(ui32)) // Add this line!
    };
