根因分析

goroutine存在无限递归或栈使用过多，导致栈溢出。

English

A goroutine has infinite recursion or excessive stack usage, causing stack overflow.

generic

解决方案

  1. 95% 成功率 Convert recursion to iteration 
    // Before: func factorial(n int) int { if n <= 1 { return 1 }; return n * factorial(n-1) }
// After:
func factorial(n int) int {
    result := 1
    for i := 2; i <= n; i++ {
        result *= i
    }
    return result
}
  2. 90% 成功率 Use a bounded depth-first search with explicit stack 
    type frame struct { n int; result int }
stack := []frame{{n: initial}}
for len(stack) > 0 {
    // process
}

无效尝试

常见但无效的做法:

  1. Increasing stack size via debug.SetMaxStack 90% 失败

    Only postpones the crash; doesn't fix the underlying bug.

  2. Using more goroutines to distribute work 80% 失败

    Each goroutine has its own stack; doesn't solve recursion issue.
