--- Comment #4 from Wes Morgan <morganw@gmail.com> ---
Just realized I hit this bug on a stacked ZFS filesystem.

Mounted on the server as:

pool-a/zfs1 on /zfs1
pool-b/zfs2 on /zfs1/zfs2

Mount /zfs1 on a remote system, and trying to copy /zfs1/zfs2/file to
/zfs1/file produces the cross-device link error and a zero-size file as the
destination.
