Prio can be lowered: working fallback to
~]# suricatasc -c version {"message": "7.0.6 RELEASE", "return": "OK"}

I think this is duplicate is #7176. You could work around this by disabling ldap in the yaml.

Alternatively, test out https://github.com/OISF/suricata/pull/11597

ldap is not enabled due to older suricata.yaml config (so also time to update this ;)

Can you post the full bt output from gdb?

LDAP is apparently enabled anyway:

Probably by default:
]# grep -i ldap /etc/suricata/suricata.yaml -c
0

]# suricata -V
This is Suricata version 8.0.0-dev (564a6c9a2 2024-08-07)

Running smooth again. Also modified suricata.yaml to reflect latest v8 config instead of the v7 setup. ldap is disabled
