Hi, I am trying to get Scigraph to work with CMUCL. So far I found what I believe is a CMUCL 0305 bug: the third/last multiple-value-setq in function device-draw-line in scigraph/draw.lisp exercises incorrect compilation of the function. I replaced it with an equivalent multiple-value-bind and that fixed the problem. (Both versions of the function worked when interpreted.) Perhaps someone wants to take a look; I'll post to cmucl-devel if I do not get any feedback. Then I encountered a similar problem with (setf bounding-rectangle-min-x) and friends in the same file. The error below is confusing (it occurs when I play with zoom in/zoom out), but I noticed that the compiler complains about missing setf methods when I recompiled the file. Then I looked at regions.lisp and the spec, and I could not find the setf methods implemented or documented. Again, the error is not raised by CMUCL 0305 when I the code in scigraph/draw.lisp is interpreted. Any suggestions are welcome.
