ssl client certs fix crash

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

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

                           libwebsocket_internal_extensions,

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

		LWS_SERVER_OPTION_REQUIRE_VALID_OPENSSL_CLIENT_CERT);

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?
