What is wrong with this line of code?

[cybermonkeyso]

I have this code that crashes my program (found it via a combination of breakpoints):

sf::Http::Request request("/servers/master/go.php", sf::Http::Request::Post);

I am using the SFML library for HTTP GET requests (basically a headless browser) for s server application in order to register a machine.
I am following this tutorial: http://sfml-dev.org/tutorials/2.0/network-http.php

The specific crash the debugger catches is this: http://puu.sh/cSZ7O/7318afe386.png

I have #pragma comment ed sfml-system.lib` and `sfml-network.lib`.

What is causing the error, and how can I fix it?
