A further aspect of this that has been bothering me, is why it doesn't show up in all the occurrences of (make-stack *cont*) that my debugging code does when called from one of the eval trap handlers. The answer (I believe) is that the eval trap handlers don't use real continuations; they use "debug objects" instead; this is controlled by the 'cheaptraps debug option, which defaults to "yes".
And one more problem ... the same problem exists in CVS head, but a similar patch doesn't fix it ... still investigating.
