[cairo] Bug?

[Steve Chaplin]

Here's a snippet which I think highlights a bug:

#include <stdlib.h>

#define LENGTH 20000
cairo_move_to (cr, .0, .50);

int i;
float x, y;
for (i=0; i<=LENGTH; i++){
    x = (float) i/LENGTH;
    y = (float) rand() / RAND_MAX;
    cairo_line_to (cr, x, y);
}
cairo_stroke (cr);


It simulates drawing lines connecting points on a graph.
With LENGTH=10,000 it works OK, with LENGTH=20,000 
cairo_snippets_gtk dies with the message 'Broken pipe'.
