Description

Version: EE-2022.03.16, deb package

Segfault happens on Ubuntu 20.04 and Linux Mint 20 (itself a derivative of Ubuntu 20.04) when the ship is destroyed (when the static should be displayed). Logs are attached from Mint box.

The game needs at least 1 remote client connected with relatively high latency (several hops, one of them through SSH tunnel). I didn't reproduce this on LAN, but with remote connection it reproduced reliably. One of the machines was Windows. Segfault on Linux happens in both configurations: when Linux is a server and Windows is a client and also vice versa. Two scenarios were tried, Basic Battle and Beacon of Light.

coredumpctl.txt
dmesg.txt
stdio.txt

(Sorry for the redactions, and I'm not comfortable posting raw cores; I still have them though and I can post additional info if you need).

This is probably not a duplicate #1741, I think I've reproduced the other one (with 2022.03.16 on Mint) and bt differs.

Research direction

Start by reviewing the attached coredumpctl.txt, dmesg.txt, and stdio.txt logs, then reproduce the destruction event with a remote client over a high-latency connection in Basic Battle or Beacon of Light. Done means the Linux client or server no longer segfaults when the destroyed-ship static is displayed in either connection configuration.
