Root Cause

Using atomic operations on non-atomic variables or misusing atomic functions, causing data races and panics.

generic

中文

在非原子变量上使用原子操作或误用原子函数，导致数据竞争和 panic。

Workarounds

  1. 90% success 
    var v atomic.Int32
v.Store(42)
val := v.Load()
  2. 85% success 
    var x int64
atomic.AddInt64(&x, 1) // correct usage

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Regular variables are not thread-safe, causing data races.

  2. 50% fail

    Redundant and may cause performance issues, but not a direct fix for misuse.
