I add Struct Pointer inside the vector and Struct Value has been changed

Question

I'm using raylib to make a little game. and here is the problem.

Struct Icon has Loc Struct that has two integer value.

When i put the Struct, Icon as a Pointer into Icons vector. value has been changed.

here is the capture of debuging.

and here is the full code.

// driver.cpp
void init() {

    InitWindow(WINDOW_WIDTH, WINDOW_HEIGHT, "Uvuntu");

    SetTargetFPS(30);

    map<string, Texture2D> mapset = loadAllImages();


    setCursor(mapset.find("cursor")->second);
    setIcons({ "File Exploer", mapset.find("icon_dir")->second, nullptr });
    setIcons({ "File Exploer", mapset.find("icon_dir")->second, nullptr });

    runIcons();
}
// icons.cpp
using namespace std;

vector<Icon*> icons;

int default_x = int(WINDOW_WIDTH  / 50);
int default_y = int(WINDOW_HEIGHT / 50);

int step = 128;

int icon_x = default_x;
int icon_y = default_y;

void setIcons(Icon icon) {
    Loc loc = { icon_x, icon_y };
    icon.loc = &loc;

    icon_y += step;
    if (icon_y > WINDOW_HEIGHT) {
        icon_y = default_y;
        icon_x += step;
    }

    cout << icon.loc->x << endl;
    cout << icon.loc->y << endl;

    icons.push_back(&icon);
}

void runIcons() {
    Loc loc = *icons.at(0)->loc;  // the problem...
    string name = to_string(loc.x) + ", " + to_string(loc.y);
    cout << name << endl;
}
// icon.cpp
using namespace std;

struct Icon {
    string name;
    Texture2D icon_img;
    Loc* loc;
};
// loc.cpp

struct Loc {
    int x, y;
};
