[lwip-users] SNMP Traps V1 vs V2c

Hello all,

I'm facing the following issue.
I'm sending a
snmp_send_trap_generic (SNMP_GENTRAP_COLDSTART);

For debug proposes I'm sending it periodically(5 seconds).

If I set:
snmp_set_default_trap_version (SNMP_VERSION_1);

it works ok. I receive periodically. My SNMP software identifies it as a cold 

If I set:
snmp_set_default_trap_version (SNMP_VERSION_2c);

It sends two Trap messages only with the following information:
Source:  Timestamp: 2 seconds
SNMP Version: 2   Trap OID: .
Community: public
Variable Bindings: 
Name: .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime
Value: [TimeTicks] 2 seconds (235)
Name: .
Value: [OID] .

After that, my system hangs on freeRTOS

If I pause the debugger it will stop on this line, please have a look at:
"11. I get stuck on the line that starts for( pxIterator = ( ListItem_t * ) &( 
pxList->xListEnd );"

So what could cause this issue by just changing V1 to V2c ?
Am I missing some configuration or handling to use V2c?
