根因分析

竞态检测器观察到对同一内存的未同步并发访问。常见于多 goroutine 访问的共享计数器、slice 或结构体字段。

English

The race detector observed unsynchronized concurrent access to the same memory. Common with shared counters, slices, or struct fields accessed from multiple goroutines.

无效尝试

常见但无效的做法:

95% 失败
The bug still exists; you just stop seeing reports while corrupt data and crashes continue.
90% 失败
Yielding does not provide memory ordering or mutual exclusion; races remain.
