I found similar malloc warnings yesterday on my cobalt qube2 around
23,Nov, and followings are from /var/log/messages.

Nov 23 18:39:03 cobalt /netbsd: Data modified on freelist: word 0 of object 0xc0
0fc500 size 256 previous type foo (invalid addr 0xdeadbeef)
Nov 23 18:39:23 cobalt /netbsd: Data modified on freelist: word 0 of object 0xc0
107100 size 256 previous type foo (invalid addr 0xdeadbeef)


uname -a output is:
NetBSD cobalt 2.99.10 NetBSD 2.99.10 (COBALT) #13: Tue Nov 23 18:35:03 JST 2004  smi@miyake.ddo.jp:/work/nb/src/sys/arch/cobalt/compile/COBALT cobalt

I booted qube2 and it happend immediately when I started cvs checkout
on fresh filesystem.

I'm sorry but not had further investigation at that time because my
qube2 is really unstable and thought it is because of memory module...
