My first attempt to run the sample code also resulted in a crashed SBCL
process, due to lost X server connection. This usually happens (with
some X servers) when the path extends to far out of the current
viewport. So I expected a scaling problem and found after some
experimentation that inserting the following before the call to
rotate_cairo_surface in plD_esc_extcairo, would fix the problem:

cairo_scale (aStream->cairoContext, 1.0 / pls->xlength, 1.0 / pls->ylength);

I hope this helps.
