Description

The code we tend to execute is

                ptmp = SCRealloc(state->ts_db,
                                 (state->ts_db_len + state->input_len));
                if (ptmp == NULL) {
                    SCFree(state->ts_db);
                    state->ts_db = NULL;
                    state->ts_db_len = 0;
                    return -1;
                }
                state->ts_db = ptmp;

                memcpy(state->ts_db + state->ts_db_len,
                       state->input, state->input_len);
                state->ts_db_len += state->input_len;
            } /* else */
            state->input += state->input_len;
            state->input_len = 0;

indefinitely.
