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-144/2018-09-07-1833/flakey.log

The failure seems to be in the "samba-py3" suite, whose build logs are available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-09-07-1833/samba-py3.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-09-07-1833/samba-py3.stdout
  
The top commit at the time of the failure was:

    wafsamba/samba_waf18: redefine flex function
    
    There is a bug in waf: flex routine adjusts its inputs against
    the task's current working directory but assumes it is being called from
    within the build variant directory.
    
    For Samba this means we adjust one level up than the actual work
    directory we use to run (bin/ vs bin/default) and flex doesn't find the
    source files.
    
    Fix the issue by creating a local override of flex definition that
    utilizes the same workd directory for both path adjustment and running
    the flex itself.
