 !!! danger "Undefined behavior"

-    Writing data to the pointee of the result yields an undefined state.
+    The pointer becomes invalid if the underlying JSON object changes.
+
+    Consider the following example code where the pointer `ptr` changes after the array is resized. As a result, reading or writing to `ptr` after the array change would be undefined behavior. The address of the first array element changes, because the underlying `std::vector` is resized after adding a fifth element.
+
+    ```cpp
+    #include <iostream>
+    #include <nlohmann/json.hpp>
+    
+    using json = nlohmann::json;
+    
+    int main()
+    {
+        json j = {1, 2, 3, 4};
+        auto* ptr = j[0].get_ptr<std::int64_t*>();
+        std::cout << "value at " << ptr << " is " << *ptr << std::endl;
+    
+        j.push_back(5);
