The occam operation performs three INs, one for each element, as does the
second variant of your C code. The first, non-working one, does a single IN
transferring three bytes, which however must be contiguous in memory at source
and destination.

You can get away with this if the data is transferred across a hard link,
because of the way they are implemented, but not if both processes are on
the same processor.
