The example is Common Lisp and the spec I meant is the Common Lisp spec.
The report-condition-with-circular-list test executes similar code on
the Lisp side.  If you run the example in CCL without SLIME it will end
up in some out-of-memory condition.  Obviously CCL doesn't detect the
cycle, and the question was whether CCL has a bug (ansi-compliance)
given that *print-circle* is t.

But it doesn't matter now as SLIME passes this test now.
