Ruby堆栈级别太深异常不是来自递归无限循环

EDIT：（已解决）实际上，它可能是由于无限循环引起的

我正在编码，添加了一个方法后，我得到了以下结果：

我很确定没有涉及无限递归循环

代码现在是以某种方式成对的，但我也得到了直接运行ruby文件的错误

感谢您对如何（获取一些信息，运行一些测试）修复问题的任何帮助，如果可能的话，无需重写整个过程

环境：

• ruby 1.9.3p194/rails 3.2.8，通过rvm安装
• 此阶段的程序仅使用rails字符串拐点函数
• 操作系统：linux kubuntu i386
• 内存4GO
• “ulimit-s”：8192（堆栈大小，kB）

我尝试过但没有成功：

• 删除了最初引发异常的代码块，但在运行时稍晚仍会引发异常
• 使用命令行“ulimit-s 20000”、“ulimit-s unlimited”设置堆栈大小。同样的错误，显然是在同一个地方（这让我觉得堆栈大小实际上没有改变）
• 降级到ruby1.9.2/rails3.1.3，得到了相同的消息
• Windows下的相同错误

应用程序上下文： 我正在编写一个大量使用ruby mixin的应用程序

此外，我还创建了一组生成mixin的类（实例/类方法模块将由其他类包含）

总而言之，我最终得到了相当多的已生成命名模块和一些自定义生成的代码，以及具有许多祖先的类

但是，当我编写位于这个库之上的程序时（不管怎么说，这就是计划），这将最终为as$省下不少痛苦

我使用的资源：

编辑：在一些代码可用于显示/测试之前，让我们将我的问题抽象为以下一个问题：除了经典的程序执行树太深的场景（交叉手指这很清楚并且意味着什么…）之外，是否还有其他情况会导致堆栈级别太深异常？

除了经典的程序执行树太深的场景之外，还有其他情况会导致堆栈级别太深的异常吗

对。因为堆栈不是按深度测量的，而是按深度测量的

def recurse(depth=0)
  recurse depth+1
rescue SystemStackError
  depth
end
=> nil
recurse
=> 8717

def recurse(depth=0)
  a,b,c = 1,2,3
  recurse depth+1
rescue SystemStackError
  depth
end
=> nil
recurse
=> 7264

def recurse(depth=0)
  a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z = *(0..25)
  recurse depth+1
rescue SystemStackError
  depth
end
=> nil
recurse
=> 3187
