Thanks for the pointer. The former discussion ended up in http://sf.net/mailarchive/forum.php?thread_id=4464869&forum_id=7152 with no indication of what branches this patch has been applied to.
Looking at 5.1.2.pre2's snmplib/snmpv3.c I still see the old code, implying that any SNMPv3 agent based on a released Net-SNMP version will stop working after ~248 days (for SNMPv3)!!? Am I missing something?
As this would qualify as a (serious) bug to me, can the patch be applied to all branches, ASAP, please?

Here's the last output from "snmpget -Dall ..." before the client gets stuck in select():
dumpv_recv: ObjID: SNMP-USER-BASED-SM-MIB::usmStatsNotInTimeWindows.0 trace: snmp_pdu_parse(): snmp_api.c, 4257: dumph_recv: Value dumpx_recv: 41 02 04 77 dumpv_recv: UInteger: 1143 (0x477) trace: _snmp_parse(): snmp_api.c, 3983: snmp_parse: Parsed SNMPv3 message (secName:xxxxxx, secLevel:authNoPriv): trace: snmpv3_get_report_type(): snmp_api.c, 3879: report: Report type: -36 trace: snmp_sess_select_info(): snmp_api.c, 5621: sess_select: for all sessions: 3
