Sig 11 Segfault in net/net-snmp net-snmp-5.1.3p4 in 4.0/i386

I've got a pretty consistent segfault:

root@br0:/home/seklecki# gdb /usr/local/sbin/snmpd
/home/seklecki/snmpd.core

Core was generated by `snmpd'.
Program terminated with signal 11, Segmentation fault.

This system 4.0-stable as of last Wednesday with a slightly modified
kernel (RAIDFrame enabled):

root@br0:/home/seklecki# uname -a
OpenBSD br0 4.0 GENERIC+RAIDFrame#2 i386 (full dmesg below)

I will try to recompile Net-SNMP from source to see if the mismatch
between GENERIC and the "recommended" 4.0 binaries is the cause. I will
also try to figure out why it's only partially being built with debugging
symbols.
