Segfault in snmp_oid_compare ()

I¡¯m using net-snmp-5.4.1 for my program

While I run the program, it crashed while updating the table

Here is my gdb trace

And source code is 


netsnmp_tdata_row *

lsmCRDPTable_createEntry(netsnmp_tdata * table_data,

                         U64 lsmCRDPTransactionID, char *lsmCRDPFileName,

                         size_t lsmCRDPFileName_len,

                         u_long lsmCRDPServerID)

{

    struct lsmCRDPTable_entry *entry;

    netsnmp_tdata_row *row;

 

    entry = SNMP_MALLOC_TYPEDEF(struct lsmCRDPTable_entry);

    if (!entry)

        return NULL;

 

    row = netsnmp_tdata_create_row();

    if (!row) {

        SNMP_FREE(entry);

        return NULL;

    }

    row->data = entry;

    entry->lsmCRDPTransactionID = lsmCRDPTransactionID;

    netsnmp_tdata_row_add_index(row, /*ASN_COUNTER64*/ASN_OPAQUE,

                                &(entry->lsmCRDPTransactionID),

                                sizeof(entry->lsmCRDPTransactionID));

    memcpy(entry->lsmCRDPFileName, lsmCRDPFileName, lsmCRDPFileName_len);

    entry->lsmCRDPFileName_len = lsmCRDPFileName_len;

    netsnmp_tdata_row_add_index(row, ASN_OCTET_STR,

                                entry->lsmCRDPFileName,

                                lsmCRDPFileName_len);

    entry->lsmCRDPServerID = lsmCRDPServerID;

    netsnmp_tdata_row_add_index(row, ASN_UNSIGNED,

                                &(entry->lsmCRDPServerID),

                                sizeof(entry->lsmCRDPServerID));

        

        netsnmp_tdata_add_row(table_data, row);

        return row;

}

 

I tried to fix this problem but failed¡¦ 

It seems to be a problem caused by invalid pointer netsnmp_tdata *
table_data 

but I couldn¡¯t find exact reason

Does anyone know or experienced similar problem? plz give me some
solution¡¦.
