We're facing the same issue. Ran a gdb against latest rsync 3.1.0. Hopefully
this helps, I'm not a C guru though.

# getacl Save
# file: Save
# owner: 200
# group: 200
user::rwx
user:201:rwx
user:600:rwx
group::r-x
group:501:rwx
mask::rwx
other::r-x
default:user::rwx
default:user:200:rwx
default:user:201:rwx
default:user:600:rwx
default:group::r-x
default:group:200:rwx
default:group:501:rwx
default:mask::rwx
default:other::r-x
