是什么导致我的HTTP服务器出现故障；退出状态-1073741819；？

作为练习，我创建了一个生成随机游戏机制的小型HTTP服务器，类似于。我在Windows7（32位）系统上编写了它，它工作得完美无缺。但是，当我在家用计算机Windows 7（64位）上运行它时，它总是会失败，并显示相同的消息：

退出状态-1073741819

。我还没有在网上找到任何引用状态代码的东西，所以我不知道它有多重要

以下是服务器的代码，并对冗余进行了删节：

package main

import (
    "fmt"
    "math/rand"
    "time"
    "net/http"
    "html/template"
)

// Info about a game mechanic
type MechanicInfo struct { Name, Desc string }

// Print a mechanic as a string
func (m MechanicInfo) String() string {
    return fmt.Sprintf("%s: %s", m.Name, m.Desc)
}

// A possible game mechanic
var (
    UnkillableObjects = &MechanicInfo{"Avoiding Unkillable Objects",
                                      "There are objects that the player cannot touch. These are different from normal enemies because they cannot be destroyed or moved."}
    //...
    Race              = &MechanicInfo{"Race",
                                      "The player must reach a place before the opponent does. Like \"Timed\" except the enemy as a \"timer\" can be slowed down by the player's actions, or there may be multiple enemies being raced against."}
)

// Slice containing all game mechanics
var GameMechanics []*MechanicInfo

// Pseudorandom number generator
var prng *rand.Rand

// Get a random mechanic
func RandMechanic() *MechanicInfo {
    i := prng.Intn(len(GameMechanics))
    return GameMechanics[i]
}


// Initialize the package
func init() {
    prng = rand.New(rand.NewSource(time.Now().Unix()))

    GameMechanics = make([]*MechanicInfo, 34)
    GameMechanics[0] = UnkillableObjects
    //...
    GameMechanics[33] = Race
}

// serving

var index = template.Must(template.ParseFiles(
    "templates/_base.html",
    "templates/index.html",
))

func randMechHandler(w http.ResponseWriter, req *http.Request) {
    mechanics := [3]*MechanicInfo{RandMechanic(), RandMechanic(), RandMechanic()}
    if err := index.Execute(w, mechanics); err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
    }
}

func main() {
    http.HandleFunc("/", randMechHandler)
    if err := http.ListenAndServe(":80", nil); err != nil {
        panic(err)
    }
}

是什么导致了这个问题？是否有一个进程可以调试这样一个神秘的退出状态？

当我运行它时，我发现以下两个错误：

template: content:6: nil pointer evaluating *main.MechanicInfo.Name
http: multiple response.WriteHeader calls

前者在web浏览器中，后者在我启动服务器的控制台窗口中

零指针问题是因为您的简化程序将GameMechanics[1:32]设置为零

第二个错误很有趣。程序中唯一调用http.ResponseWriter上任何方法的地方是index.Execute内部，这不是您的代码——这意味着html/模板中可能发生了错误。我正在用Go 1.0.2测试这个

我将_base.html放在index.html的顶部，然后将索引更改为：

var index = template.Must(template.ParseFiles("templates/index.html"))

http.WriteHeaders警告消失了

这不是一个真正的答案，而是一个你可以探索的方向

作为奖励，这里有一种编写程序的更为“可行的方法”。请注意，我简化了PRNG的使用（您不需要实例化，除非您希望多个PRNG并行），并简化了结构初始值设定项：

package main

import (
    "fmt"
    "html/template"
    "math/rand"
    "net/http"
)

// Info about a game mechanic
type MechanicInfo struct{ Name, Desc string }

// Print a mechanic as a string
func (m MechanicInfo) String() string {
    return fmt.Sprintf("%s: %s", m.Name, m.Desc)
}

// The game mechanics
var GameMechanics = [...]*MechanicInfo{
    {"Avoiding Unkillable Objects",
        "There are objects that the player cannot touch. These are different from normal enemies because they cannot be destroyed or moved."},
    {"Race",
        "The player must reach a place before the opponent does. Like \"Timed\" except the enemy as a \"timer\" can be slowed down by the player's actions, or there may be multiple enemies being raced against."},
}

// Get a random mechanic
func RandMechanic() *MechanicInfo {
    i := rand.Intn(len(GameMechanics))
    return GameMechanics[i]
}

var index = template.Must(template.ParseFiles("templates/index.html"))

func randMechHandler(w http.ResponseWriter, req *http.Request) {
    mechanics := [3]*MechanicInfo{RandMechanic(), RandMechanic(), RandMechanic()}
    if err := index.Execute(w, mechanics); err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
    }
}

func main() {
    http.HandleFunc("/", randMechHandler)
    if err := http.ListenAndServe(":80", nil); err != nil {
        panic(err)
    }
}

这是访问冲突0xC0000005的windows代码。我在谷歌上搜索了一下，发现了一些关于杀毒软件和蠕虫的投诉。但是，您提到了32位机器和64位机器上的不同行为。您是否使用了为一种体系结构设计的二进制文件？@RayToal没有，我只为每种体系结构使用了在系统上编译的二进制文件。运行编译后的二进制文件时，我没有收到退出状态消息，尽管它以同样的方式失败；我想这是因为Windows的命令提示符没有显示退出状态。当我使用go run mechanics.go时，go工具显示退出状态。编辑：我也尝试过禁用我的防病毒软件，但我遇到了同样的问题。我喜欢你的初始化和生成方法！比我写的要干净得多。当我运行它时，仍然会收到相同的退出状态消息，但是

index.Execute

似乎可能就是源代码；这是一个比我以前更好的线索。
