>Description:
The following test failure occurred:

    sscanf_whitespace: [0.001968s] Failed: /usr/src/lib/libc/tests/stdio/t_scanf.c:71: c == 'z' not met

The corresponding test code of interest is as follows:

ATF_TC(sscanf_whitespace);
ATF_TC_HEAD(sscanf_whitespace, tc)
{

        atf_tc_set_md_var(tc, "descr", "verify sscanf skips all whitespace");
}

ATF_TC_BODY(sscanf_whitespace, tc)
{
        const char str[] = "\f\n\r\t\v%z";
        char c;

        /* set of "white space" symbols from isspace(3) */
        c = 0;
        (void)sscanf(str, "%%%c", &c);
        ATF_REQUIRE(c == 'z');
}
