根因分析

两个 goroutine 在无同步的情况下访问同一内存位置，且至少一个是写操作。仅在以 -race 构建时被检测到。

English

Two goroutines access the same memory location without synchronization, and at least one is a write. Detected only when the binary is built with -race.

解决方案

  1. 95% 成功率 
    var counter atomic.Int64
counter.Add(1)
n := counter.Load()
  2. 92% 成功率 
    ch := make(chan int)
go func() { ch <- compute() }()
result := <-ch

无效尝试

常见但无效的做法:

  1. 95% 失败

    Hides the symptom; the race still corrupts data nondeterministically.

  2. 90% 失败

    Yielding does not create a happens-before relationship; race remains.
