Clang revision 113114 crashes in certain uses of nested templates. It does not
crash if a builtin type is used as argument to allocator instead of struct
pair. It does still crash if struct pair is forward declared or defined.

Unfortunately, bugzilla doesn't allow me to attach multiple files, so here is
the code:

template<typename _Tp>
struct allocator
  template<typename _Tp1>
  struct rebind
    typedef allocator<_Tp1> other;

template<typename _Alloc>
struct _Rb_tree
  typedef typename _Alloc::template rebind<char>::other _Node_allocator;
  typedef int const_reverse_iterator;

  struct _Rb_tree_impl
    : _Node_allocator

  _Rb_tree_impl _M_impl;

typedef _Rb_tree<allocator<struct pair> >::const_reverse_iterator
// END
