[arch-general] Journalctl error with systemdAssertion 'size > 0' failed at src/journal/mmap-cache.c:615, function mmap_cache_get(). Aborting. zsh: abort journalctl

[Aurko Roy]

Hi,
   I have been getting the following error whenever I try to run journalctl:

Assertion 'size > 0' failed at src/journal/mmap-cache.c:615, function
mmap_cache_get(). Aborting.
zsh: abort      journalctl

Initially I thought it had something to do with the new sealing key
functionality of systemd, so I ran journalctl --setup-keys which ran
without a problem. However this error persists even after generating the
sealing keys, so now I'm not so sure if they're related. I'm running
systemd 189-3 (with systemd-sysvcompat 189-3) from the testing repo with
permanent logging enabled (I have a /var/log/journal directory created).
Does anybody have an idea what could be causing the problem? I apologize if
this is some standard issue that may have been covered on the wiki, in
which case I would greatly appreciate if someone were to point me in the
right direction.

TIA.
