Hi all:

I've been running 1.3 on my Q700 with great results.  This machine is my
internal network's gateway over PPP.  Until a few weeks ago, I was starting
ipnat with a script that wrote a new NAT rules file, then start ipnat,
everytime a PPP link is started (due to a dynamic IP).

Then I changed the setup to one that's described in the FAQ, where I map
the entire network to 0/32, then using the command `ipf -y` to re-sync the
kernal.  The problem is that I started getting crashes with the following
message:

-----------------
Feb 21 00:18:22 homer /netbsd: Data modified on freelist: word 0 of object
0x6ca9200 size 128 previous type temp (0xdeadbeeb != 0xdeadbeef)
Feb 21 00:18:23 homer /netbsd: Data modified on freelist: word 0 of object
0x6ca0280 size 128 previous type temp (0xdeadbeeb != 0xdeadbeef)
Feb 21 00:18:23 homer /netbsd: Data modified on freelist: word 0 of object
0x6c9c300 size 128 previous type temp (0xdeadbeeb != 0xdeadbeef)
-----------------

These crashes always immediately follow a `ppp-up` and an `ipf -y`, but not
in a consistant manner.  Maybe once every 7 times or so.  What exactly does
this message mean?  And where is it coming from?

This machine runs headless and without a keyboard, so I was unable to see
if it drops into the debugger or not, not to mention a trace.
