Addresses JP-50 [CD1]
Add custom allocator parameter to wstring_convert, since we cannot allocate memory for strings from a custom allocator.
[ Batavia (2009-05): ]
We agree with the proposed resolution. Move to Tentatively Ready.
Proposed resolution:
Change [conversions.string]:
template<class Codecvt, class Elem = wchar_t,
class Wide_alloc = std::allocator<Elem>,
class Byte_alloc = std::allocator<char> > class wstring_convert {
public:
typedef std::basic_string<char, char_traits<char>, Byte_alloc> byte_string;
typedef std::basic_string<Elem, char_traits<Elem>, Wide_alloc> wide_string;
...
Change [conversions.string], p3:
-3- The class template describes an ob ject that controls conversions between wide string ob jects of class std::basic_string<Elem, char_traits<Elem>, Wide_alloc> and byte string objects of class std::basic_string<char, char_traits<char>, Byte_alloc>
(also known as std::string).
