    See Known Problem 20 in the VSX4.2.3 Release notes.
    .P
    The test expects the file created by tmpfile() to take on
    group id of the parent directory, the test is executing in.
    Since tmpfile() creates a file in /tmp (actually /var/tmp) on
    our system, it insteads takes on as the group id the effective
    group id of the process vsx1.
    .P
    This is fixed in the VSX4.2.4beta update
    Test Output
    ************************************************************************
    /tset/ANSI.os/streamio/tmpfile/T.tmpfile 2 Failed

    Test Description:
    When a call to tmpfile() creates a file, then the file permission bits
    are set to allow both reading and writing for owner, for group, and
    for other users except for those bits set in the process's file mode
    creation mask. No execute (search) permission bits are set. The user
    ID of the file is set to the process's effective user ID and the group
    ID of the file is set to the process's effective group ID or to the
    group owner of its parent directory
    Note: in FIPS and XPG4 modes the group ID of the file must be set to
    the group ID of its parent directory.
    Posix Ref: Component TMPFILE Assertion 8.2.3.9-05(B)

    Test Strategy:
    CREATE child process
    EXECUTE new program
    SUBPROGRAM:
    CREATE a temporary file using tmpfile()
    OBTAIN file descriptor for stream using fileno()
    VERIFY mode of stream by using fstat() and checking the mode,
    owner and group ids
    CLOSE stream using fclose()
    RESET the file creation mask
    CREATE a temporary file using tmpfile()
    OBTAIN file descriptor for stream using fileno()
    SET all bits in the file protection mask for this process
    VERIFY mode of stream by using fstat() and checking the mode,
    owner and group ids
    CLOSE stream using fclose()

    Test Information:
    tmpfile() did not set group id correctly when umask was 0
