I have the following function:

char * getip(void)
{
        CURL *curl_handle;

        struct MemoryStruct chunk;

        chunk.memory=NULL; /* we expect realloc(NULL, size) to work */
        chunk.size = 0; /* no data at this point */

        curl_global_init(CURL_GLOBAL_ALL);

        /* init the curl session */
        curl_handle = curl_easy_init();

        /* specify URL to get */
        curl_easy_setopt(curl_handle, CURLOPT_URL, "http://this-ip.com/micro/");

        /* send all data to this function */
        curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION, WriteMemoryCallback);

        /* we pass our 'chunk' struct to the callback function */
        curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, (void *)&chunk);

        /* some servers don't like requests that are made without a user-agent
                field, so we provide one */
        curl_easy_setopt(curl_handle, CURLOPT_USERAGENT, "libcurl-agent/1.0");

        /* get it! */
        curl_easy_perform(curl_handle);

        /* cleanup curl stuff */
        curl_easy_cleanup(curl_handle);

        return chunk.memory;
}

When I call this function for the second time in my program, it crashes. I
run curl_easy_cleanup at the end of the function but it still crashes. Why
is this?
