samba4 @4.22.1+universal: crashes on startup on Sequoia 15.5

[acediac (Acediac)]

Samba 4.22.1 crashes on my Sequoia 15.5 (arm64)

Both nmbd and smbd crash in similar ways immediately when run. Taking a hint from the other ticket, I tried compiling talloc, tevent and tdb myself and replacing the dylbs but no dice. Can anyone replicate or have any ideas?

Log from /opt/local/var/log/samba/log.smbd:

smbd version 4.22.1 started.
