In triage, the panics are happening all over the place, so this looks like the stack being smashed. Unfortunately we don't have enough detail here to investigate further. Maybe you could run your Go and C code with ASAN (go build -asan)? That might identify the issue. Note that if you're linking against other libraries that you will have to rebuild them with -fsanitize=address to get full coverage.

在分类中，到处都在发生恐慌，所以这看起来像是堆栈被砸碎了。不幸的是，我们在这里没有足够的细节来进一步调查。也许你可以用 ASAN ( ) 运行你的 Go 和 C 代码go build -asan？这可能会确定问题所在。请注意，如果您要链接到其他库，则必须重建它们才能-fsanitize=address获得全面覆盖。

use go build -asan , at runtime, it does not recur

Timed out in state WaitingForInfo. Closing.
