Any data race can cause a crash anywhere, see https://go.dev/doc/articles/race_detector so you need to fix the data races.
As for the reasons, from Google Gemini (looks accurate): Yes, a Go data race can definitely cause a runtime crash. Here's why: Undefined Behavior: When two or more goroutines access the same memory location concurrently without proper synchronization, and at least one of them is a write operation, a data race occurs. This leads to undefined behavior, which means the program can behave in unpredictable ways, including crashing. Memory Corruption: Data races can corrupt the internal state of data structures, leading to crashes or unexpected results. For example, if two goroutines try to modify the same map concurrently without proper synchronization, the map's internal structure could become corrupted, causing a crash. Panics: In some cases, the Go runtime will detect a data race and trigger a panic to prevent further damage. This results in a controlled crash with an error message, which can help you identify and fix the problem. > On Nov 19, 2024, at 12:06 AM, Lin Lin <linsite.thin...@gmail.com> wrote: > > Yes, I do agree that it's easy to write data race code. > Sorry, I didn't make it clear.
