command "du" reports wrong size ?

[Steven <steven@xxxxxxxxxxx>]

Hi
I got a strange problem. i.e. "du" command reports wrong size in FC3/4,
dd --version
dd (coreutils) 5.2.1
du --version
du (coreutils) 5.2.1

[fc3]~/tmp>dd if=/dev/zero of=dd.128 bs=1M count=128
128+0 records in
128+0 records out
[fc3]~/tmp>du -B 1M dd.128
129 dd.128

129 != 128

However, if I use the dd and du in RedHat 9:
[rh9]~/tmp>dd --version
dd (coreutils) 4.5.3
[rh9]~/tmp>du --version
du (coreutils) 4.5.3

[rh9]~/tmp>dd if=/dev/zero of=dd.128 bs=1M count=128
128+0 records in
128+0 records out
[rh9]~/tmp>du -B 1M dd.128
128 dd.128

That's correct in RH9. Is that a bug of du in the coreutils 5.2.1 ? Or
where am I wrong ?

Thanks.
