There is *no* requirement that i/o for tape (or anything else that
I know of, and I do a *lot* of SGI driver and other kernel work!) be
double aligned on SGI systems.

So there may be a bug in the gnu dd, but the double alignment
change you have made is masking the real bug, which must be
somewhere else...
