SteamCMD validation process randomly finds corruption followed immediately by segfault.

[Grntrenchman]

• Steam client version (build number or date): SteamCMD 1716584438
• Distribution (e.g. Ubuntu): Nobara (Fedora) 40
• Opted into Steam client beta?: [Yes/No] No (is that an option with SteamCMD?)
• Have you checked for system updates?: [Yes/No] Yes
• Steam Logs: steam-logs.tar.gz
• GPU: AMD

Please describe your issue in as much detail as possible:

Updating ARK dedi server through SteamCMD randomly (sometimes) causes corrupt/missing chunk errors during validation, followed by steamcmd segfault, even run back-to-back.

also confirmed by installing another dedi (7 days to die) with the same symptoms.

Steps for reproducing this issue:

1. ~/Steam/steamcmd.sh +login anonymous +app_update 294420 validate +quit
2. Run repeatedly until segfault (maybe 1/5 of the time)

I've rolled up a fresh fedora and nobara vm, and can't replicate it, even on the same drive. Not sure how to troubleshoot this further unfortunately.

Still occurring with version 1718904263.
