      Run the following dbtest:

          // Base client helper
    struct ClientBase {
        ClientBase() { mongo::lastError.reset(new LastError()); }
        virtual ~ClientBase() { }

    protected:
        static bool error() {
            return !_client.getPrevError().getField( "err" ).isNull();
        }
        static DBDirectClient _client;
    };
    DBDirectClient ClientBase::_client;

    // Runner for generated queries
    template <typename Q>
    struct GeneratedQueryRunner : ClientBase {
        virtual void run(){
            auto_ptr<DBClientCursor> cursor = _client.query(kNameSpace, Q::getQuery(), 0);
            ASSERT(!error());

            int docCount = 0;
            BSONObj result;
            while (cursor->more()) {
                ++docCount;
                result = cursor->next().getOwned();
            }
            LOG(0) << "Document Count: " << docCount;
        }
    };

struct GeneratedQuery19 {
      static BSONObj getQuery() { return query; }
      static BSONObj* getProjection() { return NULL; }
      static BSONObj query;
  };
BSONObj GeneratedQuery19::query = fromjson("{\"d\":{\"$regex\":\"(s|t|y|n)\\..\",\"$options\":'mxisi'}}");

...

    class All : public Suite {
    public:
        All() : Suite( "GeneratedQueries" ) { }
        void setupTests() {
            add< GeneratedQueryRunner<GeneratedQuery19> >();
        }
    } myall;

      Eventually this should included as part of the fuzz/nltk generated tests.

      The following query throws a FailedToParse exception when passed to fromjson():

      {"d":{"$regex":"(s|t|y|n)\..","$options":'mxsi'}}
