当我运行以下代码时:
(defun countdown (n)
(if (>= n 0)
(cons n (countdown (- n 1)))))
(countdown 100000)
我收到以下消息:
INFO: Control stack guard page unprotected
Control stack guard page temporarily disabled: proceed with caution
debugger invoked on a SB-KERNEL::CONTROL-STACK-EXHAUSTED in thread
#<THREAD "main thread" RUNNING {1002B03653}>:
Control stack exhausted (no more space for function call frames).
This is probably due to heavily nested or infinitely recursive function
calls, or a tail call that SBCL cannot or has not optimized away.
PROCEED WITH CAUTION.
Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.
restarts (invokable by number or by possibly-abbreviated name):
0: [ABORT] Exit debugger, returning to top level.
(SB-KERNEL::CONTROL-STACK-EXHAUSTED-ERROR)
如何增加堆栈空间?我不想更改上面的代码;我提供它纯粹是为了说明堆栈耗尽。
