以下のようにすると Segmentation fault を起こします。
ruby-1.9.2-p0 -e 'require "openssl"; OpenSSL::SSL::SSLSocket.new(STDIN).cert'

以下のパッチで直ると思います。
--- a/ext/openssl/ossl_ssl.c
+++ b/ext/openssl/ossl_ssl.c
@@ -1337,7 +1337,7 @@ ossl_ssl_get_cert(VALUE self)

  Data_Get_Struct(self, SSL, ssl);

• if (ssl) {

• if (!ssl) {
  rb_warning("SSL session is not started yet.");
  return Qnil;
  }

バックトレースは以下の通り。
