    Problem Summary TSD4U.00299 The test may fail because it does not ensure that the string passed to mvwadd_wchstr() is null-terminated
    Problem Text
    The following code is part of tset/CAPI.os/xcurses/bkgrnd/bkgrnd.c:

    static void test4A(void)
    {
    .....
    wchar_t wch[64];
    cchar_t wchstr[64];

    .....
    memset(wch, 0, sizeof(wch));
    for (i = 0; i < strlen(string_1); i++) {
    errno = 0;
    memset(wch, 0, sizeof(wch));
    ret_val = mbstowcs((wchar_t *)wch, &string_1[i], 1);
    if (ret_val == -1) {
    uwerrno("mbstowcs");
    return;
    }
    s2 = setcchar(&wchstr[i], wch, WA_DIM, 48, (void *)0);
    if (s2 == ERR) {
    curout(TET_UNRESOLVED, "setcchar", s2);
    return;
    }
    }
    tet_infoline("TEST: Write some text at (1,2) with attributes (DIM, COLOR_PAIR(48))");
    s2 = mvwadd_wchstr(stdscr, 1, 2, wchstr);
    .....
    }

    The above code is making the cchar_t string 'wchstr' converting
    the string 'string_1' to the wide-char string 'wch' and calling
    the function setcchar(). And the made cchar_t string 'wchstr'
    is passed to the mvwadd_wchstr() function.

    But, the the cchar_t string 'wchstr' has not been terminated by null
    before being passed to mvwadd_wchstr(). The function mvwadd_wchstr()
    expects the cchar_t string is null-terminated, according to
    the XCurses spec (add_wchnstr(), page 37, X/Open Curses, Issue 4, Version2).
    Therefore, the result of the above code will be undetermined.

    Either the cchar_t string 'wchstr' needs to be null-terminated before being
    passed to mvwadd_wchstr() or the cchar_t string array needs to be
    initialized to 0 before the for-loop.
