Making a GET or POST request from the core

I’m getting the red flash of “Out of heap memory” here. Code is this:

#include <string.h>
#define LIB_DOMAIN "exampleapp.com"

TCPClient client;

void setup() {
}

void loop() {
    client.connect(LIB_DOMAIN, 80);
    client.println("GET /status HTTP/1.0");
    client.println("Host: " LIB_DOMAIN);
    client.println("Content-Length: 0");
    client.println();
}

The app I’m sending the GET request to just returns a text response of “success” so I’m not sure exactly what’s overloading the memory. Thoughts?
