smb.conf, smbclient log and journalctl for smbd

Accessing a samba share using smbclient (like smbclient //hostname/sharename -Uusername) causes a core dump to happen on my system.
Accessing the share using a Windows 8.1 client works fine. Accessing the Windows 8.1 shares using smbclient also works fine.

Logs and smb.conf are attached.

System: Arch x86_64 with 4.1.16 Samba and smbclient (from repository)

A smbd restart actually solved it. I was trying to avoid restarting it because I tried to debug a performance issue that disappears after a restart.
But oh well, can't hurt submitting it I guess.

Hello majin3,
smb.conf, coredump are not attached on ticket. Only syslog of samba crash are there.
If you still find issues with latest version of samba, please attach coredump,smb.conf

Samba 4.1 is very old and no longer supported by the Samba Team.

Can you please try and reproduce on a current, supported version?

Thanks,
