  16 ;;; Prior to sbcl-0.7.1.38, doing something like (RECURSE), even in
  17 ;;; safe code, would crash the entire Lisp process. Then the soft
  18 ;;; stack checking was introduced, which checked (in safe code) for
  19 ;;; stack exhaustion at each lambda.
  20
  21 ;;; Post 0.7.6.1, this was rewritten to use mprotect()-based stack
  22 ;;; protection which does not require lisp code to check anything,
  23 ;;; and works at all optimization settings.  However, it now signals a
  24 ;;; STORAGE-CONDITION instead of an ERROR, so this test needs revising
