How to disable "cycle detected in the references of" check?

[nh2]

I'm trying to build systemd with -O0 -g for debugging a problem.

I get the error

cycle detected in the references of ‘/nix/store/5h1ighmqw55q7xfz3hnwqlq54dfvx3v2-systemd-234’

How can I disable this feature?

Btw, these are those references:

But I guess I don't care too much about this systemd specific as long as I can quickly turn off that check for debugging any package, no matter what strings it puts into its binary.

For reference, you can't disable the "feature". Nix currently relies on the store not containing cycles (e.g. when doing GC AFAIK).
