Did you check that you're using the same versions of everything (OS,
octave, gnuplot) on those two different computers?

There really can't be. For starters, we're talking about three separate
issues with different likely reasons. So there's no "the" cause for
gnuplot to inform you about.
The first error being described most probably is caused by an I/O buffer
limitation being hit somewhere between octave and the main gnuplot
executable (pipe buffer, Windows message queue). In effect, some of the
data are getting garbled or lost on the way, and gnuplot tries to
interpret remaining inline data (input lines containing of just numbers)
as commands, which it rather obviously can't. Given those
circumstances, there really can't be a meaningful error message.
There's no context left to reconstruct possible meaning from.
The broken pipe issue with binary data is probably either the same
problem in a different disguise, or a generic incapability of the
communication channel to handle binary data. Hard to tell without at
least knowing the OS platform and gnuplot version.
The third issue could be anything --- we gnuplot people don't generally
know what those octave commands actually end up sending to gnuplot.
Without that, there's nothing we can do to help.

So what's keeping you from upgrading it? 2.61 has been around for well
over two years now!
