您使用的是什么版本的 Go ( go version )？

go version go1.10rc1 darwin/amd64

这个问题会在最新版本中重现吗？

是的

您使用的是什么操作系统和处理器架构（ go env ）？

你做了什么？

如果它在插件中调用 http.Get 方法。 它发生像runtime: unexpected return pc for runtime.goexit called from 0x4460ce0这样的致命错误

您可以使用此演示 (https://github.com/nzlov/testplugin) 重现该问题

复制步骤

  1. 构建插件
    go build --buildmode=plugin post.go

  1. 构建主应用程序
    go build main.go

  2. 跑步
    。/主要的

在linux上，它运行良好。 它只发生在 darwin/amd64 上。

你期待看到什么？

运行没有致命错误

你看到了什么？
