            Bug ID: 19613
           Summary: -fdelayed-template-parsing vs. out-of-line definition
                    of inner class method
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW

The following code fails to compile with -fdelayed-template-parsing:

struct HeapTypeConfig {
  static void from_bitset();
};

template <class Config>
struct TypeImpl  {
  struct BitsetType;

  static void Any() {
    BitsetType::New();
  }
};

template<class Config>
struct TypeImpl<Config>::BitsetType {
  static void New() {
    Config::from_bitset();
  }
};


/tmp/a.cc:17:5: error: use of undeclared identifier 'Config'
    Config::from_bitset();
    ^
/tmp/a.cc:22:29: note: in instantiation of member function
'TypeImpl<HeapTypeConfig>::Any' requested here
  TypeImpl<HeapTypeConfig>::Any();
                            ^
