with help from #lisp, I have found a way to reproduce an 'Unhandled
memory fault at #x90' without using slime:

If you have http://common-lisp.net/project/bordeaux-threads/ installed:

run this two or three times get to the error:

(bt:make-thread (lambda () (with-plot-window
   (loop for (x y) in '((1 1) (-2 4) (3 9) (-4 16) (5 25))
      do (plot-point x y)
        (sleep 1)))) :name "test-bug")


where (defparameter *plot-device* "xcairo")

See: http://paste.lisp.org/display/105741.
