Bug #29958 cURL https request fails when connecting to IP (not domain)

When attempting to connect to an IP address (not a domain) over SSL using cURL (7.9.5), there is no response, no errors, etc.  I get nothing.  When I test the same script with a domain (a different server), I get a response as expected.  When I test it with the correct IP address over HTTP (non-secure), I also get a response as expected.

The problem, however, is that the server that I have to connect to for the app I'm building does not have a domain, only an IP address and it must be a secure connection.  

I admit that I could be missing something, but I can't figure out what it is and I've tested it pretty thoroughly under multiple scenarios.

Reproduce code:

// use appropriate IP, of course
$ch = curl_init(""); 
curl_setopt($ch, CURL_POST, 1);
curl_setopt($ch, CURL_POSTFIELDS, $postdata);
curl_setopt($ch, CURL_ERROR, 1);
curl_setopt($ch, CURL_RETURNTRANSFER, 1);
$retval = curl_exec($ch);

// print result for testing
echo $retval;

Expected result:
The echo statement should print the web page data from the IP to the screen, and it does when I test with non-secure IP or domain.

Actual result:
Nothing. The echo statement doesn't seem to print anything.  No cURL errors, no results, no PHP warnings or errors.

I should mention that this same code DOES work on a different requesting server (FreeBSD 4.4; PHP 4.2.3)

curl 7.9.5 was released some 30 months ago. Do I need to say more?

Good point Daniel, marking this as bogus. Upgrade first!

Nope, it's not a problem with the curl version (as I knew it wouldn't be).  I upgraded to 7.12 and still had the problem.  Turns out I had to set the CURLOPT_VERIFYHOST to false so it wouldn't try to resolve the domain name with the SSL certificate.

I don't know if you'd still call it a bug, but this would have been much easier to solve if I had received some kind of error message to that effect.  I had PHP error messages turned on and the CURLOPT_ERROR option turned on, so I should have gotten something, but I didn't.

Anyway, it's fixed now.
