尾递归优化发生在Visual Studio 10的x64调试，但不是在释放？ [英] tail recursion optimization happens in visual studio 10 x64 debug but not in release?

问题描述

原来我得到了在x86的模式计算器例外。正如我注意到，64将优化尾递归，所以我在切换到64位编译。和优雅地在调试模式中摸索出。但是当我试图运行发布代码..它扔计算器再次..任何可能的原因是什么？

originally I got a stackoverflow exception in x86 mode. As I noticed that x64 would optimize tail recursion so i switched to compile in x64. And it worked out gracefully in debug mode.. However when I tried to run the release code.. it throwed stackoverflow again.. any possible reason?

推荐答案

在应用尾递归优化是复杂和多变的规则。

The rules for when tail recursion optimizations are applied are complicated and ever-changing.

我会强烈建议您的不的依赖从一个点的正确性尾递归。

I would strongly recommend that you don't rely on tail recursion from a correctness point of view.
