Hello,

I am having problems saving lisp images.  I am using Lucid Common Lisp
Version 4.0 on a DEC-Ultrix machine.  

When tring to save an image with CLOS loaded, sometimes I can "successfully"
save images and sometimes I cannot.  By successfully, I mean that I can use
the image.  Most of the time I save an image with no warnings or whatever,
but when I go to run the image, it chokes on me.  E.g.:

;;; Warning: Stopping scan due to bad frame
;;; Warning: Stopping scan due to bad frame
>>Error: 
         ###### An internal system error has been detected ######
         Missed frame with wrong number of arguments

Only CLOS has been loaded when I save the image.  I save the image using the
following command:

(disksave "~/clos" :full-gc t)


Very occasionally, I am able to save some images successfully. However, most
of the time I am not ablt to.

Any ideas?

Thanks,
Gary Livingston

I asked JonL White about this.  (He used to work at what was then
Lucid before Harlequin purchased Lucid's Lisp assets, and JonL moved
to Harlequin.)

JonL says he thinks that a long time ago, then-Lucid shipped
out a fix for a problem with the same symptoms as you describe. He
sounded surprised that if you have a properly registered copy of it
that you wouldn't have gotten the fix from then-Lucid ages ago when it
still existed.  (In other words, maybe if you look around in your
distribution kits, it might be there and you're just not noticing.
But if it's not, he seemed to have no real help to offer because he 
also notes that then-Lucid later stopped supporting the DEC platforms
(VAX and DEC-Ultrix).

As I mentioned, the technology in question was later purchased by
Harlequin.  Later versions (for other platforms) continue to be
maintained and sold by Harlequin under the trade name Liquid Common 
Lisp (still LCL, for continuity).  Harlequin has not revived the DEC
platform support for LCL.

Sorry...

Thanks for the information.  I'll look around in my directories.
