C26444 Avoid unnamed objects with custom construction and destruction (es.84)

问题

Can anyone help me solve the problem?? Before when I had only one method for class, which was void show(vector &list, string &filter), get&display functions were in it, then i decided to split those functions into vector get() & void display() but when i return a new modified vector from vector get() the error appears:

C26444 Avoid unnamed objects with custom construction and destruction (es.84).

Here's a short code example for realization:

#include <iostream>
#include <vector>
#include <string>

using namespace std;

class Test
{
//variables
};

class Base
{
public:
    virtual vector<Test>get(vector<Test>& list, string& filter) = 0;
    virtual void display() = 0;
};
class A : public Base
{
    string a;
    string b;
    vector<Test> aList;

public:
    vector<Test>get(vector<Test>& list, string& filter)
    {
        //modifying info and placing to vector<Test> aList
        return aList;
    }
    void display()
    {
        //show aList
    }
};

int main()
{
    vector<Test> list;
    //define list
    string filter;
    //define filter

    Base* object = new A();
    object->get(list, filter);
    object->display();
    return 0;
}
