Your previous email indicated it was not crashing with SSLv23_method():
"While the above code didn't work. I couldn't reach the server. Though
the SSL_connect() didn't crash, it returned as..."

So my advice was meant for that scenario.

If its actually crashing then we need to see a backtrace and a wireshark
packet capture.

You should not get a compilation error. Please post the steps you took
to compile the library and the compilation error you received.
