Since all args to LOGP seem to be well defined, I'm not sure what's causing this.

btw, this fault seems to be triggered because my MCC+MNC LAC/RAC config in the hNodeB mismatches the CN config

Taken a detour via --enable-sanitize builds and resolving sanitizer complaints, a test of hnbgw after this is pending.

I could move to a different machine to continue / re-install or somesuch, but instead I really would like to understand precisely what is going on here. Might ask for some assistance soon.

Various patches have been merged, and it is not clear exactly which one fixes it, but I can no longer reproduce the error (which used to trigger 100% of the time before).
