Hi,

I am using NET-SNMP 5.1. I have seen at table_iterator.c the next lines of code 
in function netsnmp_table_iterator_helper_handler:

table_info = netsnmp_extract_table_info(request);
if (table_info->colnum < tbl_info->min_column - 1) {

Should it be checked whether table_info is NULL before executing if statement? 
Should table_info ever be NULL?

Thank your for any comments or explanations,

David
