Description: ber_printf support for O format
Fix Description: When calling ber_printf with the 'O' format, the corresponding argument must be a struct berval *. If the bval argument is NULL, nothing is written (i.e. it is safe to use a NULL here). Otherwise, bval->bv_len bytes from bval->bv_val will be written to the output.
