Embedded Pion server crashes on request handling

[vktr]

I'm embedding Pion in a small console application (MSVC-12.0). Unfortunately it crashes when handling a simple HTTP GET request.

I've built it with boost_1_57_0, openssl-1.0.2 and zlib-1.2.8 and no logging.

Here's a small example program reproducing the issue,

#include <pion/http/server.hpp>
#include <pion/http/response_writer.hpp>

using namespace pion;
using namespace pion::http;

struct test_server {
    void start() {
        m_server = pion::http::server_ptr(new pion::http::server(4500));
        m_server->add_resource("/", boost::bind(&test_server::handle_request, this, _1, _2));
        m_server->start();
    }

    void handle_request(http::request_ptr& req, tcp::connection_ptr& conn) {
        http::response_writer_ptr writer(
            http::response_writer::create(
            conn,
            *req,
            boost::bind(&tcp::connection::finish, conn))); // Crashes in this callback

        writer->write("hello world");
        writer->send();
    }

    pion::http::server_ptr m_server;
};

int main() {
    test_server svr;
    svr.start();

    while (1) {
        Sleep(0);
    }
}

It crashes in the &tcp::connection::finish callback with the following stack trace,

I tried this on OSX and it seems to work fine.
