The mongod server crashes when the c++ client sends a bad ensureIndex(). Here's the code (http://pastebin.com/d744f024)

void statstore_mongo::init(vector<string>& options) {
dbconn_.reset(new DBClientConnection());
try

{ string host = options.size() > 1 ? options[1] : "localhost"; dbconn_->connect(host); BSONObjBuilder b; b.append("stat_id", 1); b.append("word", 1); BSONObj obj = b.obj(); dbconn_->ensureIndex("retweet", obj); // This crashes the server on the second ensureIndex(). dbconn_->ensureIndex("hashtags", obj); dbconn_->ensureIndex("location", obj); dbconn_->ensureIndex("keywords", obj); }

catch (const UserException& e)

{ string what("Unable to open mongo database connection: "); what.append(e.what()); throw runtime_error(what); }

}

And here's a partial log:
