Segmentation fault when running hello world test program

I have got segmentation fault when running a simple hello world example.
Here is my main code with a simple handler

#include
using namespace drogon;

int main(int argc, char *argv[]){

bool result = app().reusePort();
cout << result << endl;
app().registerHandler(
"/",
[](const HttpRequestPtr &,
std::function &&callback) {
auto resp = HttpResponse::newHttpResponse();
resp->setBody("Hello, World!");
callback(resp);
},
{Get});

app().setThreadNum(1).addListener("127.0.0.1", 6666).run();
}
