Hmm.  Here's what it did for me on Windows XP (maybe the bug is in the
underlying Windows functions, which has since been fixed in your Windows
version?)

Breakpoint 1, main () at foo.c:5
5       {
(gdb) n
6         if (setlocale (LC_ALL, "ja_JP.eucJP") != NULL)
(gdb)
8             char input[] = "B\217\253\344\217\251\316er";
(gdb)
13            memset (&state, '\0', sizeof (mbstate_t));
(gdb)
14            if (mbrtowc (&wc, input + 1, 1, &state) == (size_t)(-2))
(gdb)
16                input[1] = '\0';
(gdb)
17                if (mbrtowc (&wc, input + 2, 5, &state) != 2)
(gdb)
18                  return 1;
(gdb)
