Bug#336310: nscd dies (Aborted) because of corrupted(?) persistent-cache file

[Franklin PIAT <fpiat@bigfoot.com>]

Package: nscd
Version: 2.3.5-6
Severity: normal


Hello,

Symptom: 
	nscd dies suddenly
Disgnostic:
	when running nscd in debug modes, it dies with the error :
		12870: handle_request: request received (Version = 2)
		from PID 12877
		12870:  GETFDHST
		12870: provide access to FD 8, for hosts
		12870: Reloading "ldap.dmz1.klabs.be" in hosts cache!
		12870: Reloading "www.tnt.com" in hosts cache!
		nscd: hstcache.c:364: cache_addhst: Assertion
		`hst->h_addr_list[1] == ((void *)0)' failed.
		Aborted
	
	Note that i didn't "used" the record www.tnt.com and that 
	nscd always crashes with that record.

	running "strace nscd -d"
		epoll_wait(10, 11716: Reloading "www.tnt.com" in hosts
		cache!
		nscd: hstcache.c:364: cache_addhst: Assertion
		`hst->h_addr_list[1] == ((void *)0)' failed.
		bfa02940, 100, 29988)    = -1 EINTR (Interrupted system
		call)
		+++ killed by SIGABRT +++

	I have a copy of the faulty table i can provide.

Workaround:
	- invalidates (i.e. purge) faulty table cache with "nscd -i
	  hosts" (while nscd is running !)
	- disable "persistent" option in /etc/nscd.conf

Thanks,

Franklin PIAT
