           Summary: Default value for std::map in a class method doesn't

Sample code

The following declaration 
  class Foo {
    double bar(const std::map<int, int>& baz = std::map<int,int>());
  };
causes Clang 3.3. to issue a compilation error:
  error: expected ')'
  double bar(const std::map<int, int>& baz = std::map<int,int>());
                                                              ^
  note: to match this '('
  double bar(const std::map<int, int>& baz = std::map<int,int>());
            ^
  error: expected '>'
  double bar(const std::map<int, int>& baz = std::map<int,int>());
                                                         ^
  2 errors generated.
  Compilation failed

See the attached file for more examples.

The same code compiles correctly in Visual Studio 2012 on Windows and with GCC
4.8.1 on Linux.

Note that std::map and std::vector were used as an example only. It seems that
any other one- and two-parameter template leads to the same error.
