 ## Remarks
 
 You tried to use the [`dynamic_cast` operator](../../cpp/dynamic-cast-operator.md) or [`typeid` operator](../../cpp/typeid-operator.md), which requires [Run-Time Type Information](../../cpp/run-time-type-information.md) (RTTI), without enabling it. To enable RTTI, recompile with [`/GR`](../../build/reference/gr-enable-run-time-type-information.md).
+
+## Example
+
+The following example generates C4541:
+
+```cpp
+// C4541.cpp
+// compile with: /W1 /GR-
+
+#include <typeinfo>
+
+struct Base
+{
+    virtual ~Base() {}
+};
+
+struct Derived : Base {};
+
+int main()
+{
+    Derived derived;
+    Base* pointer_to_base = &derived;
+
+    dynamic_cast<Derived*>(pointer_to_base);   // C4541
+
+    typeid(*pointer_to_base);   // C4541
+    typeid(pointer_to_base);    // OK
+}
+```
