The app is just a test echo server. JSON sent in the body of a
POST request is echoed back to the client. On Pop!_OS it works
fine but on Windows it responds, there's a delay of about 10
seconds and then it crashes with the error:
```

Here's the code:
```d

import std.json, std.stdio;
void main() {
auto settings = new HTTPServerSettings;
settings.port = 8080;
settings.bindAddresses = ["::1", "127.0.0.1"];
auto router = new URLRouter;
router.get("*", serveStaticFiles("public/"));
router.post("/", &onPost);
auto listener = listenHTTP(settings, router);
scope (exit) { listener.stopListening(); }
logInfo("App listening at http://127.0.0.1:8080/";);
runApplication();
}
static string handlePost(string req) {
return req;
}
void onPost(HTTPServerRequest req, HTTPServerResponse res) {
try {
auto jsr = async(&handlePost,
req.json.toString()).getResult();
res.contentType("application/json; charset=utf-8");
res.writeBody(jsr);
} catch (Exception e) {
res.contentType("text/plain; charset=utf-8");
res.writeBody(e.msg);
}
}
```
Also when you launch/build the app with dub there's a shed load
of deprecation warnings, e.g.:
```
\Local\dub\packages\vibe-d-0.9.5\vibe-d\stream\vibe\stream\wrapper.d(334,23):
Deprecation: reference to local variable `this` assigned to non-scope parameter
`bytes` calling `writeToStream`
```
I'm a D newbie so it's quite possibly something I'm doing wrong
...
The -1073741819 error is OxC0000005 in hex.
And C0000005 on Windows is a access violation exception,
indicating that you are trying to access memory that doesn't
belong to your process. Possibly a 'buffer overrun' access
exception - but I'm not sure in this case.
Unfortunately I'm not experienced with vibe at all - so I can't
help with your code.
Just google 'Windows error C0000005' for more info.
