Pipe commands will fail at SR10.2 / SR10.2.p if the first component of
the pipeline manages to complete before the pipeline is set up (it is
not just history that does this, but it is one of the easiest ones since
it is built-in to csh).

I have called it in and APR'ed it -- it will not be fixed in SR10.2,
but is supposedly fixed in SR10.3.
