When compiled with gcc 4.1.1 on Linux the program below runs successfully to completion as it should. When compiled with stdcxx the facet returns a to_next value that is greater than the number of internal (wchar_t) characters actually produced by the conversion and consequently the program aborts.
$ cat t.cpp && make t && ./t
#include <cassert>
#include <cwchar>
#include <locale>
int main ()
{
const std::locale utf8 ("en_US.UTF-8");
typedef std::codecvt<wchar_t, char, std::mbstate_t> UTF8_Cvt;
const UTF8_Cvt &cvt = std::use_facet<UTF8_Cvt>(utf8);
const char src[] = "abc";
wchar_t dst [2] = { L'\0' };
const char* from_next;
wchar_t* to_next;
std::mbstate_t state = std::mbstate_t ();
const std::codecvt_base::result res =
cvt.in (state,
src, src + 1, from_next,
dst, dst + 2, to_next);
assert (1 == from_next - src);
assert (1 == to_next - dst);
assert ('a' == dst [0]);
