Possibly both.  You really should have specified a trange to get a 
proper circle with one turn.  Yours is about 1.6 turns, making it hard 
to know which area is supposed to be filled.  I.e.

	plot [0:2*pi] sin(t), cos(t) w filledcurves

might have worked better (it does here with 4.6.4 on Windows).  And you 
should have mentioned which version of gnuplot you observed this with.

Hans-Bernhard,

thanks - this helped a lot, works on different versions of gnuplot and
solves my issue.
