Summary: 5.7.1 crashes on solaris

Initial Comment:
Solaris:
$ uname -a
SunOS avdesk2.enaza.ru 5.10 Generic_142910-17 i86pc i386 i86pc
snmpd:
$ /usr/local/net-snmp/sbin/snmpd -v

NET-SNMP version:  5.7.1
Web:               http://www.net-snmp.org/
Email:             net-snmp-coders@lists.sourceforge.net

snmpd is build from sources. Sometimes it crahes. The cause is unknown: may work for \
a week, may crash after couple of hours.

Backtrace:
