I'm using 7.20.0.

curl_global_init() gets called before starting worker threads.
though curl here only deals with HTTP POST requests, below SSL related options are set in code.
curl_easy_setopt(m_curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_easy_setopt(m_curl, CURLOPT_SSL_VERIFYHOST, 1);
curl_easy_setopt(m_curl, CURLOPT_SSLENGINE_DEFAULT, 1);
But besides curl worker threads, there are some other threads using SSL, and in those threads curl_easy_escape, only this curl API, is called. Problem in there?
