&gt;What does the code *around* this fragment look like?  &gt;In particular, how is the variable 'requestvb' assigned?Here is the code which handles response:Response_handle(unsigned char *Buffer,int size, netsnmp_request_info *requests){&nbsp;&nbsp;&nbsp; ptr = (unsigned char *)pbuf;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; netsnmp_variable_list *Vbsvd = NULL;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (Vbsvd = requests-&gt;requestvb; Vbsvd; Vbsvd = Vbsvd-&gt;next_variable )&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if(*((unsigned int *)ptr) != EXCEPTION_NO_SUCH_INSTANCE)&nbsp;&nbsp;&nbsp; {&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; type= *((int *)ptr);&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; switch(type)&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; {&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp
 ; &nbsp;&nbsp;&nbsp; case TYPE_STRING:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; snmp_set_var_typed_value(requestvb,AS
 N_OCTET_STR,(u_char *) ptr, str_len);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case TYPE_INT:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; snmp_set_var_typed_value(requestvb,ASN_INTEGER, (u_char *) ptr, sizeof(INT));&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case TYPE_IPADDR:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; snmp_set_var_typed_value(re
 questvb,ASN_IPADDRESS, (u_char *) ptr, sizeof(unsigned long));&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; default:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return SNMP_ERR_RESOURCEUNAVAILABLE;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return SNMP_ER
 R_NOERROR;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }and requestvb at the time of debugging looks like this(for the 1st attribute):    (gdb) p *requestvb$6 = {next_variable = 0x0, name = 0x
 b7a393b0, name_length = 13, type = 5 '\005', val = {integer = 0xb7a395b0, &nbsp;&nbsp;&nbsp; string = 0xb7a395b0 "", objid = 0xb7a395b0, bitstring = 0xb7a395b0 "", counter64 = 0xb7a395b0, floatVal = 0xb7a395b0, &nbsp;&nbsp;&nbsp; doubleVal = 0xb7a395b0}, val_len = 0, name_loc = {1, 3, 6, 1, 1, 1, 144, 1, 122, 1, 1, 4, 0 &lt;repeats 116 times&gt;}, &nbsp; buf = '\0' &lt;repeats 39 times&gt;, data = 0x0, dataFreeHook = 0, index = 0}&gt;
Please *always* give a sensible amount of context.
Sorry for this.

Girish
