Details:

The following code gives and error in Octave-3.4.3 but works in Octave-3.2.3:


x = linspace(0,2*pi,100);
y = sin(x);

ax = plotyy (x, y, x-1, y+1);

plot(x,y,x,cos(x));
legend('sin','cos');


The error occurs after the last call to legend and no legend is drawn.  The
error is:


error: get: invalid handle (= -31.1477)
error: evaluating argument list element number 1
error: evaluating argument list element number 1
error: invalid empty index list
error: called from:
error:   /usr/local/share/octave/3.4.3/m/plot/legend.m at line 136, column 47
