Arch Linux

Summary and Info:

Since today, i'm running pacman -Syu on one server and i get a "segmentation fault".
Not unable to solve this issues in any way ... :
- there is at this time no space issues (/tmp has space, /var/log also, same for /var/cache/ ...)
- replacing mirrors by other mirrors in etc/pacman.d/mirrorlist does not help
- removing the /var/lib/pacman/sync db files does not help

Stack :

Content of /var/lib/pacman/sync :
-rw-r--r-- 1 root root 5,2M 2020-08-22 09:50 community.db
-rw-r--r-- 1 root root 132K 2020-08-21 21:13 core.db

-rw-r--r-- 1 root root 1,7M 2020-08-22 09:36 extra.db

I can write files in that folder without any issues.

root:sync/ # ll [10:57:24]

Steps to Reproduce:

Just run pacman -Syu

Seems NOT directly the same than FS#53904.
