            Bug ID: 16410
           Summary: Access control ignored in member template function
           Product: clang
           Version: 3.3
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: w.shane.grant at gmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Access control (e.g. private) seems to be ignored for template functions
calling other template functions that do no explicitly instantiate them. 
Consider the following example:

class Base
{
  private:
    template <class T>
    void foo(T t) {}
};

class Derived : public Base
{
  public:
    template <class T>
    void bar(T t)
    {
      foo(t);
    }
};

int main()
{
  Derived d;
  d.bar(5);
}

This compiles (clang version 3.3 (trunk 178896) (llvm/trunk 178895)) even
though foo should be inaccessible to Derived.
