Root Cause

A goroutine has infinite recursion or excessive stack allocation, causing stack overflow

generic

中文

协程存在无限递归或过多的栈分配，导致栈溢出

Workarounds

  1. 90% success Refactor recursive function to iterative approach 
    func factorial(n int) int {
    result := 1
    for i := 2; i <= n; i++ {
        result *= i
    }
    return result
}
  2. 85% success Use tail recursion with proper termination condition 
    func factorialTail(n, acc int) int {
    if n == 0 {
        return acc
    }
    return factorialTail(n-1, n*acc)
}

Dead Ends

Common approaches that don't work:

  1. Increasing stack size via runtime.GOMAXPROCS 95% fail

    GOMAXPROCS controls parallelism, not stack size; stack limit is fixed by runtime

  2. Using more goroutines to distribute work 80% fail

    More goroutines do not reduce stack usage per goroutine; each still has its own stack
