+An invalid number of generic parameters was passed to an intrinsic function.
+
+Erroneous code example:
+
+```compile_fail,E0094
+#![feature(intrinsics)]
+
+extern "rust-intrinsic" {
+    fn size_of<T, U>() -> usize; // error: intrinsic has wrong number
+                                 //        of type parameters
+}
+```
+
+Please check that you provided the right number of type parameters
+and verify with the function declaration in the Rust source code.
+Example:
+
+```
+#![feature(intrinsics)]
+
+extern "rust-intrinsic" {
+    fn size_of<T>() -> usize; // ok!
+}
+```
