    Test Suite VSU version 5.0.2
    Test Identification xcurses/key_name 5
    Problem Summary TSD4U.00246 This test is not deriving its invalid wide character correctly.
    Problem Text
    Here are the important parts of CAPIxcurses/fkey_name/fkey_name1.c:

    static void test5A(void)
    {
    char *key;
    wchar_t wch;
    int ret_val, i;

    ....
    ret_val = mbtowc(&wch, 0x0, 1);
    if (ret_val == -1) {
    uwerrno("mbtowc");
    return;
    }
    key = (char *)key_name(wch);
    tet_infoline("TEST: Return value");
    if (key == NULL) {
    ....
    }

    The test is assuming that "mbtowc(&wch, 0x0, 1)" saves an invisible
    wide character at "wch". But according to XSH5, p. 504, "wch" is not
    required to be loaded if the second argument is a null pointer:

    If s [second argument] is not a null pointer, mbtowc() determines the
    number of bytes that constitute the character pointed to by s. ....
    If the character is valid and pwc [first argument] is not a null
    pointer, mbtowc() stores the wide-character code in the object
    pointed to by pwc.

    The value at "wch" is uninitialized and not affected by mbtowc(), so the
    result of the subsequent key_name() is meaningless.
