{code}
		protected internal virtual int replace_s(int c_bra, int c_ket, System.String s)
		{
			int adjustment = s.Length - (c_ket - c_bra);
            		if (current.Length > bra) 
			//<--!! 'bra' is '0'. Caller(s): TurkishStemmer.r_postlude() -> TurkishStemmer.r_append_U_to_stems_ending_with_d_or_g() -> insert() -> replace_s()
    				current.Replace(current.ToString(bra, ket - bra), s, bra, ket - bra);
            		else
                		current.Append(s);
