Use gcl? :-)
I don't see any issues with current CVS with cmucl, but I haven't
finished running the entire demo yet. I don't have sbcl to try this.
One option is to run maxima with the -g option. When you get the error,
you'll be in the Lisp debugger and you can type backtrace to get a stack
trace. This should help in finding the problem.
Oh, the demo finished successfully just now.
