    Problem Text
    This test may fail on implementations that define ut_line
    to be less than 24 characters in length.

    getutxent() Test 1 and several other utmpx tests fail because they copy a
    string into the "ut_line" member of struct utmpx that is longer than the
    space allocated for ut_line. This trashes other members of the utmpx
    structure, and then the test does not read back what it thinks it wrote
    out. The problem is even worse in CAPI/SRC/LIB/capi_utmpx/mk_utmpx.c in
    function write_several_entries(), where a malloc'ed area is also overrun.

    The solution is to first make sure the resulting string is not longer than
    sizeof(utmpx.ut_line).

    The following tests will also fail for this reason:

    getutxid() Test 2-8, 10-13
    getutxline() Test 1
    pututxline() Test 1, 2
