Path Name:  /hp-ux_patches/s700_800/10.X/PHCO_7757

Symptoms:
        PHCO_7757:
        awk does not allow to reset ARGC and ARGV
        in BEGIN action.

        PHCO_7494:
        awk split function causes coredump when a formal
        argument is used as the "array" parameter.

        PHCO_7171:
        When the last field of an input record to awk(1)
        is NULL, awk(1) does not recognise it, causing
        the reported NF to be one less than the actual.

        PHCO_6611:
        Size of data segment of awk(1) increases unchecked.
        10.x awk is slower compared to 9.X awk and also
        it cannot write to non-text files.

Defect Description:
        PHCO_7757:
        awk does not allow to reset ARGC and ARGV
        in BEGIN action.

        PHCO_7494:
        awk split function causes coredump when a formal
        argument is used as the "array" parameter.

        PHCO_7171:
        awk(1) does not recognise the last input field
        if it is a NULL.

        PHCO_6611:
        10.X awk leaks memory when calling user functions
        with "$" arguments.($0,$1...)
        10.x awk is slower compared to 9.X.Also it
        differs functionally.

Installation Instructions:
        Please review all instructions and the Hewlett-Packard
        SupportLine User Guide or your Hewlett-Packard support terms
        and conditions for precautions, scope of license,
        restrictions, and, limitation of liability and warranties,
        before installing this patch.
        ------------------------------------------------------------
        1. Back up your system before installing a patch.

        2. Login as root.

        3. Copy the patch to the /tmp directory.

        4. Move to the /tmp directory and unshar the patch:

                cd /tmp
                sh PHCO_7757

        5a. For a standalone system, run swinstall to install the
            patch:

                swinstall -x autoreboot=true -x match_target=true \
                        -s /tmp/PHCO_7757.depot

        5b. For a homogeneous NFS Diskless cluster run swcluster on the
            server to install the patch on the server and the clients:

                swcluster -i -b

            This will invoke swcluster in the interactive mode and
            force all clients to be shut down.

            WARNING: All cluster clients must be shut down prior to the
                     patch installation.  Installing the patch while the
                     clients are booted is unsupported and can lead to
                     serious problems.

            The swcluster command will invoke an swinstall session in which
            you must specify:

                alternate root path  -  default is /export/shared_root/OS_700
                source depot path    -  /tmp/PHCO_7757.depot

            To complete the installation, select the patch by choosing
            "Actions -> Match What Target Has" and then "Actions -> Install"
            from the Menubar.

        5c. For a heterogeneous NFS Diskless cluster:

                - run swinstall on the server as in step 5a to install
                  the patch on the cluster server.

                - run swcluster on the server as in step 5b to install
                  the patch on the cluster clients.  The cluster clients
                  must be shut down as described in step 5b.

        By default swinstall will archive the original software in
        /var/adm/sw/patch/PHCO_7757.  If you do not wish to retain a
        copy of the original software, you can create an empty file
        named /var/adm/sw/patch/PATCH_NOSAVE.

        Warning: If this file exists when a patch is installed, the
                 patch cannot be deinstalled.  Please be careful
                 when using this feature.

        It is recommended that you move the PHCO_7757.text file to
        /var/adm/sw/patch for future reference.

        To put this patch on a magnetic tape and install from the
        tape drive, use the command:

                dd if=/tmp/PHCO_7757.depot of=/dev/rmt/0m bs=2k
