That took care of it, Mark. Thanks. I will look at adding the patch
shortly.

Any idea on that mem.c INSIST? It seems it only happens if I give
nsupdate a blank line at some point, with no associated action. It
doesn't seem to cause any problems here, so no big deal. But it seems
like it should probably get closed up. Is there a place I can file it as
(low priority) bug? Er... just realized it could be due to the -O3
CFLAGS. I'll recompile without that when I do the patch.

Thanks again.

Examples:

# nsupdate -y ...
] quit
// no error

# nsupdate -y ...
]
] quit
mem.c:866: INSIST((((ctx->pools).head == ((void *)0)) ? isc_boolean_true
: isc_boolean_false)) failed.
Aborted

# nsupdate -y ...
] server 127.0.0.1
] update add test2.example.com. 120 A 10.1.1.1
]
] quit
// no error

# nsupdate -y ...
]
] server 127.0.0.1
] update add test2.example.com. 120 A 10.1.1.1
]
] quit
mem.c:866: INSIST((((ctx->pools).head == ((void *)0)) ? isc_boolean_true
: isc_boolean_false)) failed.
Aborted
