Hello curl gurus.

I am facing a problem while sending an HTTPS request with curl...

Here is an extract of the code, all error code being removed, and curl_global_init() and curl_global_cleanup() being called in main:

bool FB_call_webservice(const char* AA_param)
{
  string VH_json_string = FH_format(
      "{\"param\":\"%s\"}",
       AA_param);

  CURL* VH_curl;
  struct curl_slist* VH_headerlist;
  CURLcode VI_res;
  long VI_http_code;

  VH_curl = curl_easy_init();

  VH_headerlist = curl_slist_append(NULL, "Content-Type: application/json; charset=utf-8");
  VI_res = curl_easy_setopt(VH_curl, CURLOPT_HTTPHEADER, VH_headerlist);

  VI_res = curl_easy_setopt(VH_curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
  VI_res = curl_easy_setopt(VH_curl, CURLOPT_NOSIGNAL, true);
  VI_res = curl_easy_setopt(VH_curl, CURLOPT_CONNECTTIMEOUT, 5);
  VI_res = curl_easy_setopt(VH_curl, CURLOPT_FOLLOWLOCATION, true);
  VI_res = curl_easy_setopt(VH_curl, CURLOPT_SSL_VERIFYHOST, false);
  VI_res = curl_easy_setopt(VH_curl, CURLOPT_URL, GH_url.c_str());
  VI_res = curl_easy_setopt(VH_curl, CURLOPT_POSTFIELDS, VH_json_string.c_str());
  VI_res = curl_easy_setopt(VH_curl, CURLOPT_POSTFIELDSIZE, VH_json_string.size());

  VI_res = curl_easy_perform(VH_curl);
  VI_res = curl_easy_getinfo(VH_curl, CURLINFO_RESPONSE_CODE, &VI_http_code);

  curl_slist_free_all(VH_headerlist);
  curl_easy_cleanup(VH_curl);

  return (VI_http_code == 200);
}

I have the following crash systematically while calling curl_easy_perform:

The versions installed are:
> rpm -qa | grep openssl
openssl-0.9.8e-20.el5
> rpm -qa | grep curl
curl-7.15.5-9.el5_6.3

I don't understand what's happening. It works correctly when the URL specified is http, but it crashes in https. Certificate is correctly installed, the https target server is successfully reached when calling it through the curl command-line tool, but it crashes in my application... Did I miss something? Is it a known bug in these versions?

Thanks for your attention,
Daniel
