POWhat is causing my HTTP server to fail with "exit status -1073741819"?
text
Body
copied!<p>As an exercise I created a small HTTP server that generates random game mechanics, similar to <a href="http://inventwithpython.com/randommechanic.html" rel="nofollow">this one</a>. I wrote it on a Windows 7 (32-bit) system and it works flawlessly. However, when I run it on my home machine, Windows 7 (64-bit), it always fails with the same message: <code>exit status -1073741819</code>. I haven't managed to find anything on the web which references that status code, so I don't know how important it is. </p> <p>Here's code for the server, with redundancy abridged:</p> <pre><code>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) } } </code></pre> <p>In addition, the <a href="http://pastebin.com/naxzbxPc" rel="nofollow">unabridged code</a>, the <a href="http://pastebin.com/c069YJjp" rel="nofollow">_base.html template</a>, and the <a href="http://pastebin.com/d87Hd0WZ" rel="nofollow">index.html template</a>.</p> <p>What could be causing this issue? Is there a process for debugging a cryptic exit status like this?</p>
