Golang 运行 main.go 时频繁崩溃，出现 0xc0000005 异常

Golang小白一枚，正在不断学习积累知识，现将学习到的知识记录一下，也是将我的所得分享给大家！而今天这篇文章《Golang 运行 main.go 时频繁崩溃，出现 0xc0000005 异常》带大家来了解一下##content_title##，希望对大家的知识积累有所帮助，从而弥补自己的不足，助力实战开发！

我是 golang 新手，已经使用 gin 和 gorm 开发了一个基本的 rest api。 api 工作正常，代码中没有错误。 main.go 文件如下：

package main
import (
    "fmt"
    "os"

    "github.com/gin-gonic/gin"
    "github.com/joho/godotenv"
    "github.com/usman2661/todo-crud-go/controllers"
    "github.com/usman2661/todo-crud-go/models"

    // "github.com/gin-contrib/cors"
    "net/http"
)

func godotenvvariable(key string) string {

    // load .env file
    err := godotenv.load(".env")

    if err != nil {
        fmt.println("error loading .env file")
    }

    return os.getenv(key)
}

// cors middleware
func cors(c *gin.context) {

    // first, we add the headers with need to enable cors
    // make sure to adjust these headers to your needs
    c.header("access-control-allow-origin", "http://localhost:4200")
    c.header("access-control-allow-methods", "*")
    c.header("access-control-allow-headers", "*")
    c.header("content-type", "application/json")

    // second, we handle the options problem
    if c.request.method != "options" {

        c.next()

    } else {

        // everytime we receive an options request,
        // we just return an http 200 status code
        // like this, angular can now do the real
        // request using any other method than options
        c.abortwithstatus(http.statusok)
    }
}

func main() {

    router := gin.default()

    host := godotenvvariable("host")
    port := godotenvvariable("dbport")
    user := godotenvvariable("user")
    dbname := godotenvvariable("dbname")
    password := godotenvvariable("password")
    sslmode := godotenvvariable("sslmode")

    models.connectdatabase(host, port, user, dbname, password, sslmode)

    router.use(cors)

    router.get("/todos", controllers.gettodos)          //  get all the todos
    router.post("/todos", controllers.createtodo)       // create a new todo
    router.get("/todos/:id", controllers.gettodo)       // fetch a single todo using id
    router.put("/todos/:id", controllers.updatetodo)    // update and existing todo id has to be passed
    router.delete("/todos/:id", controllers.deletetodo) // delete a todo using the id

    router.get("/catagory/:username", controllers.getcatagories) //  get the different catagories

    router.run()
}

但是，偶尔它会在运行时不断崩溃，之后它就不再工作，我必须重新启动我的机器来修复它然后它才能工作。它抛出以下异常

exception 0xc0000005 0x0 0x7fff91b70fff 0x1a34e3f0000
pc=0x1a34e3f0000

runtime: unknown pc 0x1a34e3f0000

我在网上进行了大量研究，但找不到解决此问题的答案。是否有任何解决方案可以永久解决此问题而不是重新启动电脑。

完全异常：

解决方案

程序将被go运行时终止。即使您的 http 服务器可能具有恢复功能，也无法从死锁中恢复。
