The autobuild log of the failure is available here:

The failure seems to be in the "samba-nt4" suite, whose build logs are available here:
The top commit at the time of the failure was:

commit 80c9219d6079532f31c4e415906a606d395af6e8

    s3/locking: Fix assertion check on lock reference count
    lock_ref_count will always hold the old value prior to change. Thus it
    would mean that if lock_ref_count is 0 the new value is already -1 which
    is not expected here. Therefore it is better to make sure that it is
    always greater than 0 rather than >= 0.
