Incidentally, ubase dd also has this bug:

    $ yes | dd ibs=1 count=1 >/dev/null
    57 records in
    57 records out
    65536 bytes (0 MB) copied, 1 s, 0.000000 MB/s

    $ yes | dd ibs=1 obs=1 count=1 >/dev/null
    57 records in
    57 records out
    65536 bytes (0 MB) copied, 1 s, 0.000000 MB/s

but it works correctly with bs:

    $ yes | dd bs=1 count=1 >/dev/null
    1 records in
    1 records out
    1 bytes (0 MB) copied, 1 s, 0.000000 MB/s
