libcurl 7.29.0 crashes under following conditions:
The initialization followed by cleanup of multi interface causes segfault due to dereferencing NULL pointer. This code wont work:
~~~~~~
:::c
int main(void)
{
    curl_global_init(CURL_GLOBAL_ALL);
    CURLM *multi_handle = NULL;
    multi_handle = curl_multi_init();
    if (multi_handle)
        curl_multi_cleanup(multi_handle); // << Segfault here (multi.c:1776)
    curl_global_cleanup();
    return 0;
}
~~~~~~
