Hi,

I'm trying to use libcurl within a dynamic library function to submit
an XML request over https, but am consistently getting core dumps
during the SSL handshaking (see below).

I've tried using curl 7.10.3 and 7.10.4 with OpenSSL 0.9.6i.
The code seems to work OK when ran as part of a stand-alone executable,
but the problem occurs when executed as .so plugin.

Also, I'm using OpenSSL to establish SSL-encrypted connections to LDAP
(based on LDAP C SDK) from within the same plugin, and that works OK.

Can anyone shed some light on what could be going wrong?

The initialization of the curl handler is as follows:

...
curl = curl_easy_init();
...

if ( curl ) {
   SSL_RESULT = curl_easy_setopt(curl, CURLOPT_SSLENGINE_DEFAULT, 1);
   if ( SSL_RESULT != 0 ) {
       sprintf(*ppszErrorMsg, "CURL SSL Engine Initialization Failed\n");
       return false;
   }
   curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0);
   curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 1);
   curl_easy_setopt(curl, CURLOPT_RANDOM_FILE, "/dev/urandom");

   curl_easy_setopt(curl, CURLOPT_NOPROGRESS, 1);
   curl_easy_setopt(curl, CURLOPT_FAILONERROR, 1);
   curl_easy_setopt(curl, CURLOPT_DEBUGFUNCTION, my_trace);
   curl_easy_setopt(curl, CURLOPT_VERBOSE, CURL_VERBOSE);
   curl_easy_setopt(curl, CURLOPT_URL, "https://localhost/myurl");

   headerlist = curl_slist_append(headerlist, "iv-user:myuser);
   headerlist = curl_slist_append(headerlist, "Content-type:text/xml");
   curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist);

   curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteMemoryCallback);
   curl_easy_setopt(curl, CURLOPT_FILE, (void *)&chunk);
   curl_easy_setopt(curl, CURLOPT_POST, 1);
   curl_easy_setopt(curl, CURLOPT_POSTFIELDS, szRequestXML);

   res = curl_easy_perform(curl);
   ...
}
...
