Ultrix 3.1C "dd" seg faults writing to disk

[Ian! D. Allen [CGL]]

I can't remember reading about all this stuff in the release notes:

    # dd of=/dev/rmt0h bs=64k < /etc/termcap
    2+1 records in
    0+0 records out

    # dd of=/dev/rmt0h bs=32k < /etc/termcap
    write: No such device or address
    3+0 records in
    0+0 records out

    # dd of=/tmp/foo
    Segmentation fault

I thought I had a corrupted dd, but it has the right "sum" according
to the /usr/etc/subsets/*.inv file.  What am I doing wrong?
