根因分析

主 goroutine 阻塞在没有任何其他 goroutine 能满足的 channel 接收/发送上；运行时检测到完全无活动后中止。

English

Main goroutine blocks on a channel receive/send that no other goroutine can satisfy; runtime detects total inactivity and aborts.

解决方案

  1. 92% 成功率 
    ch := make(chan int, 1)
ch <- 42 // non-blocking with buffer
v := <-ch
_ = v
  2. 90% 成功率 
    select {
case v := <-ch:
    _ = v
case <-time.After(2 * time.Second):
    return errors.New("timeout waiting for value")
}

无效尝试

常见但无效的做法:

  1. 95% 失败

    Sleep does not create a sender; deadlock still occurs and adds nondeterminism.

  2. 99% 失败

    Deadlock is a fatal runtime error, not a panic; recover never runs.
