wget_wch problem

When running the following program on Solaris 8 with
ncurses(ncurses-5.3-20031004-patch) and zh_CN.GB18030 I get a seg fault at
wget_wch (stack trace below)

It works fine for any other locale.

Any ideas.

#include <signal.h>
#include <locale.h>
#include <curses.h>
#include <errno.h>
#include <stddef.h>

main(int argc, char ** argv) {
        WINDOW *win;
        wint_t in_wc;
        int ret_c;

        initscr(); nonl(); noecho(); raw(); erase(); refresh();

        setlocale(LC_ALL, "");

        win = newwin(20, 60, 0, 0);

        clearok(win, 1); touchwin(win); wrefresh(win);
        do {
                errno = 0;
                ret_c = wget_wch(win, &in_wc);
        } while ((ret_c == ERR) && (errno == EINTR));

The back trace from gdb,

Program terminated with signal 11, Segmentation Fault.
