At the start of the routine:

    /*
     * use built-in storage for smaller values
     */
    if (len <= sizeof(vars->buf)) {
        vars->val.string = (u_char *) vars->buf;
        largeval = 0;
    }


Remember that vars->val is a *union* structure.
Pointing 'val.string' to 'vars->buf' has exactly the
same effect as pointing 'val.objid' there.
