Description

Note: this issue has been created as a private issue -- I think we can remove the private setting since this is not traffic induced.

When configuring Suricata 7.x/master with multi-tenants, a SIGSEGV occurs:

The same configuration does not crash with master-6.0.x

I've attached the configuration files that I'm using -- they contain pathnames that will require modification

Add include: /path/to/tenant.haml to suricata.yaml
