the current master tree.

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 b20fd15e04ce9292f90a7f70f4184e43034b4b9d

    smbd: implement SMB_FILE_NORMALIZED_NAME_INFORMATION handling
    Windows 10 (1803 and higher) support and use
    SMB_FILE_NORMALIZED_NAME_INFORMATION calls over the network. As a
    fallback (in case the server don't support it) the client traverses all
    path components, which is very expensive.
    Implementing SMB_FILE_NORMALIZED_NAME_INFORMATION is very cheap for us
    as the open already went through unix_convert() and we have the
    information the client is asking for.
