Description Fabrice Bellet 2004-11-12 10:02:22 EST

Description of problem:
the bug described here
applies to the net-snmp version shipped in FC3. The one-liner fix
provided at the same place works for me. So, maybe it is worth to
integrate it in an updated package for FC3 ? (rawhide net-snmp is
older than the  FC3 package currently)

Best wishes,

PS : a second pointer needs to be initialized too, so the patch that
works for me is :

Patch added to net-snmp-5.1.2-12. Should be in rawhide already.

Will this be issued as an update package for FC3?  SEGV errors are
rather serious.  On one of my servers, snmpd consistently dies anytime
you try to start the service.
