           Product: clang
           Version: trunk
          Platform: Macintosh

My project doesn't build with the built-in as yet (I filed bugs and I fixed a
few of them). I heard that I can pass -no-integrated-as in this case. Turns out
that works even worse. Here's a reduced test case:

$ cat assert.cc

template<typename _Iterator>
class __normal_iterator {
  _Iterator _M_current;
};
template<typename _Tp>
class vector {
  public:
    typedef __normal_iterator<const _Tp*> const_iterator;
    const_iterator begin() const { return const_iterator(); }
};
void copy(vector<int>::const_iterator, vector<int>::const_iterator, int) {}
void __merge_adaptive(vector<int>::const_iterator __first,
                      vector<int>::const_iterator __middle,
                      int __len1,
                      int __len2,
                      int __buffer,
                      int __buffer_size,
                      int __comp) {
  copy(__first, __middle, 0);
}
void SortStrings16(vector<int>* strings) {
  __merge_adaptive(strings->begin(), strings->begin(), 0, 0, 0, 0, 0);
}
$ g++  -gdwarf-2   -no-integrated-as -c assert.cc   #works
$ /Users/thakis/src/llvm/Release/bin/clang++  -gdwarf-2   -no-integrated-as -c
