check_curl: segfault #2167
Description
Hello!
The following check_curl command throws an segfault, while it works with check_http:
'/usr/lib64/nagios/plugins/check_curl' '-S' '--sni' '-H' '<domain>' '-I' '<proxy-ip>' '-f' 'follow' '-j' 'CONNECT' '-p' '8880' '-u' '<url-to-follow>'
HTTP CRITICAL - Invalid HTTP response received from host on port 80: cURL returned 28 - Connection timed out after 10001 milliseconds
when using -vvv, the verbose output reveals an segfault:
...

</head><body>
<h1>Moved Permanently</h1>
<p>The document has moved <a href="<url-to-follow>">here</a>.</p>
</body></html>
* Seen redirect location (null)
Segmentation fault (core dumped)
When using the proxy fqdn instead of the proxy ip, the segfault appears directly in the check output. Its reproduceable.
