Memory usage? about gumbo-query HOT 1 OPEN

I have test the following code with valgrind

void test_issue() {
std::string html = "

            CDocument d;
            d.parse(html);
            CSelection c = d.find("#something");
    }

}

valgrind --tool=memcheck ./example

I think the result is ok.
