The autobuild test system (on sn-devel-184) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

The failure seems to be in the "samba-ad-dc-2" suite, whose build logs are available here:
The top commit at the time of the failure was:

commit eb2e29c354ceb7ffe3bcc786929006a6cf9b13ea

    s3-smbcontrol: Replace && with || to declare variables in do_sleep()
    --enable-developer internally use --enable-selftest alongside. But when
    configured only with --enable-selftest the following code block becomes
     #if defined(DEVELOPER) && defined(ENABLE_SELFTEST)
            unsigned int seconds;
            long input;
            const long MAX_SLEEP = 60 * 60; /* One hour maximum sleep */
    making those variables undeclared for further use. Therefore replace &&
    with || to have those variables declared with --enable-selftest
    configure option.
