Always get buffer overflow when snmptrapd calls traphandle, on FC12 & 13.

Can anyone kindly help me on this issue?

I'm using Core13 for Zabbix 1.8.2, and trying snmptrap works on Zabbix.

However, every time snmptrapd gets a snmp notification, it aborts. With debug mode, it reports a buffer overflow detected. I've tried another Fedora core 13 and a core 12, with net-snmp 5.5. On these three systems, snmptrapd behaves the same.

Here is my snmptrapd.conf,

disableAuthorization yes
traphandle default mail -s trap [email protected]

I triggered snmptrapd with,
snmptrap -Ci -v 2c -c public localhost "" "1.3.6.1.4.1.8837.4.1.2.1.2.1.6.4" 1.3.6.1.4.1.8837.4.1.2.1.2.1.6.4 int 500

Same result I got with my firewall snmp traps. Some other different scripts replaced in traphandle default, got the same. 

A small portion of debug info listed,
