>Description:
Machine reliably panics at end of zfs receive.

The options (-DRp on send, -Fdu on receive) are just what I use when replicating zfs filesystems between my Solaris boxes.  Dedup is not enabled on the test filesystems.

core.txt file attached.
>How-To-Repeat:
(with pool 'a' already existing - empty or having other filesystems doesn't matter)
zfs create a/test
zfs snapshot a/test at snap
zfs send -DRp a/test at snap > /tmp/test.zfs
zfs destroy -r a/test
zfs receive -Fdu a < /tmp/test.zfs

The same panic occurs if I use a zfs dump from this machine, too:
# uname -a
SunOS andy 5.11 snv_134 i86pc i386 i86pc Solaris
