"allrecord_mutex_lock() failed: Invalid argument" looks like a C 
interpretator's complaint. I thought maybe there's a conflict between 
gcc and Clang of FreeBSD's base system. So I removed gcc and recompiled 
Samba. But no, the errors are exactly the same.

I also have another FreeBSD machine (10.3) where some months ago I built 
Samba 4.4.5 ADDC, and there "net rpc" commands work.
