Segmentation fault 11 error on such simple code? [duplicate]

I am very new to C++... I'm trying to implement a simple stack with Linked List..I know segmentation fault has to do with memory but all I did was make a stack with one element in it and it's only throwing "Segmentation fault: 11" that I have no clue where it came from. Here's my code:

#include <iostream>
using namespace std;

struct Node{
     int data;
     struct Node* link;
 };

Node* Push(int, Node*);

int main(){
    struct Node* top = nullptr;
    top = Push(3, top);
}

Node* Push(int data,  Node* top){
    struct Node* temp = (struct Node*) new Node();
    temp->data = data;
    temp->link = top->link;
    top = temp;
    return top;
}
