ps2pdf dumps core: on one of four deb 11 hosts

[Tom Browder <tom.browder@gmail.com>]

I have four Linux hosts running Debian 11. I have ghostscript
installed on each. Each is currently updated.

Of the four, only one dumps core on running ps2pdf on the same ps file:

    $  man -t ls > ls.ps; ps2pdf ls.ps

Note the single host that dumps core started life as a Debian 9 host
and on it I did rolling upgrades to 10, then 11.

Note it is also the only host running the UFW firewall. Checking its status:

    # ufw status
    Status: active

    To                     Action        From
    --                      ------           ----
    22/tcp               ALLOW     Anywhere

    22/tcp  (v6)      ALLOW      Anywhere (v6)

Any hints as to how to proceed?

Thanks.
