Created attachment 7575
  --> http://llvm.org/bugs/attachment.cgi?id=7575
example showing that the const pointers are allowed to modify the instance it
points to

It happens in the following 2 cases:
1) even if you explicitly specify the class type and specify "const"
2) when you you "cons id" as the data type

Overview
=======
const pointer should not be allowed to be modify the instance it points to

Actual Behavior
============
const pointer is allowed to be modify the instance it points to

Expected Behavior
=============
const pointer shouldn't be allowed to be modify the instance it points to.

Example:
========
The example attached shows the 3 cases of using const pointers.
In 2 cases, no error is thrown and in 1 case error is thrown and seems
inconsistent
