[cfe-dev] libc++'s unorderd_map bug?

[oroppas]

Hi,

Both calng++ and g++ with libc++ fail to compile the attached piece of code,
$ clang++ -std=c++0x -stdlib=libc++ unordered_map.cpp

In file included from ./unordered_map.cpp:1:
/usr/include/c++/v1/string:1031:35: error: no type named 'char_type' in
      'Parameter'
    typedef typename traits_type::char_type              value_type;
            ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~

(lots of error messages)


However, it can be compiled against libstdc++
$ calng++ -std=c++0x unordered_map.cpp

I'm not sure if the program conforms strictly to the standard or it's a bug
in libc++.
Any comment will be appreciated.

Thanks,

Ryuta
