After updating to macOS beta 4, go test -cover is throwing "fatal error: unexpected signal during runtime execution"

Question

Go build 和 go test 仍在运行。

在更新到 macOS beta 之前，我使用测试覆盖工具没有遇到任何问题。

"go test" 工作正常；但是，所有覆盖率测试命令都抛出此错误（go test -coverprofile=coverage.out 抛出相同的问题）。

如果有人知道如何解决这个问题，我将不胜感激！

Answer 1

是的，go 运行时存在一些问题。我在升级到 Sierra macOS 版本后遇到了这个问题。

关于此问题的原因进行了长时间的讨论 link;

基本上，只需更改 "defer" 语句的位置即可解决此 issue.More 详细更改为 here。

我通过安装 "go1.8beta2.darwin-amd64.pkg" 测试版 Go 解决了这个问题。我不再面临这个问题了。

注意：根据 this discussion，此问题未在 1.7 中修复。
