Details:

The following code crashes:


x=0:20;
y=x;
yy=20:-1:0;
hold on
grid on

line_handles(1) = line(x, y,  'Color', 'r');
line_handles(2) = line(x, yy, 'Color', 'k');

lh = legend(line_handles, {'y','yy'});
set(lh, 'orientation', 'horizontal');
set(lh, 'location', 'southeast');


The second call to set() gives the following error:

error: set: invalid handle (= -10.632)


Note that grouping together the last three lines (in a single call to
legend()) works fine.
