core dump

Hi all,

have recently had a problem where net-snmp cores

this is from config.log

  $ ./configure --disable-set-support --with-mib-modules=ucd-snmp/disk
ucd-snmp/diskio ucd-snmp/lmSensors ucd-snmp/loadave ucd-snmp/proc
 ucd-snmp/logmatch ucd-snmp/file disman/event disman/schedule host smux
mibII/mta_sendmail --with-cc=gcc --disable-shared --enable-static
--with-default-snmp-version=2 --enable-embedded-perl

hostname = ***deleted***
uname -m = sun4v
uname -r = 5.10
uname -s = SunOS
uname -v = Generic_127111-11

and this is from a gdb session.

(gdb) bt

Looking at the code...
