Confirmed with rev 1.9 of subr_mchain.c.
However, I notice that this only happens with files of 8145 bytes size
or larger.
[server]
# for i in `jot 512 7680`; do
dd if=/dev/zero of=$i bs=$i count=1
done 2>/dev/null
[client]
$ for i in `jot 512 7680`; do
cp /smb/urchin/pub/bytes/$i . || break;
done
cp: ./8145: Bad address
If I truss the cp process, I get this:
[...]
open("/smb/urchin/pub/bytes/8145",0x0,00) = 3 (0x3)
open("./8145",0x401,00) = 4 (0x4)
mmap(0x0,8145,0x1,0x1,3,0x0) = 671461376 (0x2805b000)
I don't have my laptop set up as a serial debugging client now, so
that's as far as I can go. :-(
Ciao,
Sheldon.
