The agent_auth_cb is actually not used for pairing but for authorization, so whether it's RequestPinCode or RequestPasskey wont matter for the above backtrace. Anyway, I was never able to reproduce the exact same issue as you had, but I did find two places needing some extra checks (one in adapter.c and another in agent.c). So it'd be good if you could give the latest git a spin and see if you can still reproduce the crash.
