[Bug c++/32410] New: Const functions in template don't give access errors with this until instantiated.

["coppro at users dot sourceforge dot net" <gcc-bugzilla at gcc dot gnu dot org>]

If you create a const member function to a template class, it seems to be able
to change a non-mutable member of the function by using the this pointer. The
following illegal code compiles:

template <typename T>
class Class
 {
  unsigned int i;
 public:
  void foo () const
   {
    this->i++;
   }
 };

However, if Class<whatever>::foo is instantiated, then it gives an error for
changing the constant data member. However, if you remove the "this->" line,
the access errors occur even without an instantion. This is inconsistent
behavior. They should both cause errors at the same point.
