Is (1 . 1) of type CONS a cons? => NIL
without signalling an error.
+154:
+ There's some sort of problem with aborting back out of the debugger
+ after a %DETECT-STACK-EXHAUSTION error in sbcl-0.7.1.38. In some cases
+ telling the debugger to ABORT doesn't get you back to the main REPL,
+ but instead just gives you another stack exhaustion error. The problem
+ doesn't occur in the trivial case
+ * (defun frob () (frob) (frob))
+ FROB
+ * (frob)
+ but it has happened in more complicated cases (which I haven't
+ figured out how to reproduce).
