    Problem Summary PG4U.00070 This test may fail on non-ASCII IUTs.
    Problem Text
    This test may fail on non-ASCII IUTs.

    These assertion as written is non-portable to a non-ASCII platform,
    for the same reason as cited in TSD4U.00124, however the actual
    symptoms of the failure as seen in the journal are different.
    The AF_UNIX SOCK_DGRAM portion of the assertion is failing because
    the sendto() called from the server (in the subroutine unix_server)
    fails EINVAL because no sockaddr is filled in. (It was corrupted
    for the same reason cited in TSD4U.00124.) The subsequent select
    by the client times out because there is nothing to read, and the
    test fails.

    The following picture helps clarify this:

    SERVER CLIENT
    ------- ----------
    socket
    bind
    recvfrom socket
    connect
    write
    select (on read)
    sendto (fails - EINVAL
    no sockaddr filled in)
    select times out - nothing
    to read.

    The problem becomes even clearer when compared with the similar
    picture for the AF_UNIX SOCK_STREAM case:

    SERVER CLIENT
    ------- -------
    socket
    bind
    listen
    accept socket
    connect
    receive write
    select (on read)
    send
    receive select completes - ok to read



    (Note also that the failures for the STREAMS portion of this
    assertion is independent of this problem and will be covered by
    a seperate IR to be submitted in the near future.)

    We recommend this request be refused.

    Patch VSU 4.1.0D provides a workaround for these failures. We
    reccommend that the implementation be required to apply this
    patch prior to making a single branding run.
