Root Cause

goroutine中访问了超出切片范围的索引，导致panic。

goroutine中访问了超出切片范围的索引，导致panic。

Workarounds

  1. 90% success 
    if i < len(slice) { v := slice[i] }
  2. 85% success 
    go func(){ defer func(){ if r := recover(); r != nil { log.Println(r) } }(); /* ... */ }()

Dead Ends

Common approaches that don't work:

  1. 60% fail

    检查不充分，可能仍有边界情况。

  2. 70% fail

    recover只能恢复，但数据可能未处理。
