Looks like a bug. I have a potential fix, can you try it? You will
need to apply auth-dummy-ganesha.patch to Ganesha, and
auth-dummy-ntirpc.patch to ntirpc. You will likely have to re-run
cmake to get ntirpc to regenerate it's exports.
thank you for the patches. They solve the segfault in
nfs_rpc_create_chan_v40(), but later another one occurs in clnt_vc_call():

Due to the authentication failure chan->auth is set to NULL in
nfs_rpc_create_chan_v40(). Eventually chan->auth is passed to
clnt_vc_call() in the cc_auth field of a struct clnt_req.
