Issues with Mixed Strings, Inegers in Multi OID SNMPGET Request

Hello all. I have written a program that performs several SMNPGET's in a single call. The problem is that when I parse the results into an array using the following function:

for (vars = response->variables; vars; vars = vars->next_variable) {
snprint_value(snmp_oids[i].result, sizeof(snmp_oids[i].result)-1, vars->name, vars->name_length, vars);
i++;
}

I get a blank string for the values that are parsed as STRINGS. We first noticed this with the UCD/NET SNMP load average OID values. They would normaly return "0.01", etc. as STRING.

The problem is not consistent either, but working with a few users, I have found a way to isolate and remove the problem, but I would rather just eliminate it from happening at all. First off, if I run in Cygwin windows I experience no problems.

Also, if a user, on a system that is experiencing the problem, deletes/moves all the MIB files poited to by the MIBDIRS environment variable, the problem also goes away.

In addition, if that same user uses the SNMPGET application, the information that is returned is accurate.

This appears to be associated with MIB parsing. The only problem is that I don't know what library calls to make to prevent this error from occuring. Any help would be appreciated.
