>Description:
basic_filebuf<CharT, Traits> fails to link if CharT is any type other than char or wchar_t or if Traits is any type other than char_traits<CharT>.

I think the attached program is required to link and run, in particular it satisfies the requirements for Traits in 21.1.1, 27.1.2 and 27.8.1.1.
