[Libwebsockets] WebSocket Server, SSL Operation

I am using a slightly older version of web sockets, but don't see any
changes in the release0.6 that seem to affect the issue I ran into.

(libwebsockets-71e53691756fd420c409538c71b010997f06f414 is the version I
am using).



I run a web socket server that requires clients to present a


context_ssl_ = libwebsocket_create_context(wssPort_, wssIpAddr_.c_str(),


                           cert_path.c_str(), key_path.c_str(), -1, -1, 



I am getting a crash in the OpenSSL_verify_callback().

The SSL_get_ex_data() call is returning NULL


I could not find a call to SSL_set_ex_data() for server mode operation.


Has anyone seen this crash in the newer versions?



I have not been able to get my build env setup to build the latest

Or I would have verified and written a bug for it.
