504 Gateway Time-out when calling curl_exec() in PHP with SSL peer verification (CURLOPT_SSL_VERIFYPEER) off

I'm seeing a strange problem with nginx (1.5.2 on Windows) and PHP
(5.4.8 on Windows).

Whenever I make a cURL request with PHP's curl_exec() function to a
secure URL (https protocol), and I disable peer verification, like this


nginx responds with a "504 Gateway Time-out".

If I set CURLOPT_SSL_VERIFYPEER to TRUE, nginx responds with a "200 OK",
although curl_exec() returns false, which is expected due to the
verification failure (I'm using a self-signed certificate in nginx).

I have tried executing the same script under Apache and it functions as
expected with peer verification disabled.

Thank you for any help,
