void main() {
  Pointer<Int64> p1 = calloc<Int64>(3);
  try {
    Pointer<Void> p2 = new Pointer.fromAddress(p1.address);
    Expect.throws(() {
      p2.elementAt(1);
    });
  } finally {
    calloc.free(p1);
  }
}

This should have always been a compile error, but was accidentally a runtime error before.

https://dart-review.googlesource.com/c/sdk/+/276102 turns this into a compile error.

Please fix the test to expect a compile-time error instead.
