The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-11-14-0822/flakey.log

The failure seems to be in the "samba" suite, whose build logs are available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-11-14-0822/samba.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-11-14-0822/samba.stdout
  
The top commit at the time of the failure was:

commit 3634e20c7603103b0f2e00e5b61cc63f905d780d
Author: Jeremy Allison <jra at samba.org>
Date:   Mon Nov 12 11:37:31 2018 -0800

    s3: lib: nmbname: Ensure we limit the NetBIOS name correctly. CID: 1433607
    
    Firstly, make the exit condition from the loop explicit (we must
    never write into byte n, where n >= sizeof(name->name).
    
    Secondly ensure exiting from the loop that n==MAX_NETBIOSNAME_LEN,
    as this is the sign of a correct NetBIOS name encoding (RFC1002)
    in order to properly read the NetBIOS name type (which is always
    encoded in byte 16 == name->name[15]).
