very long lines in /etc/hosts cause cupsd to segfault

[canavan]

Binary package hint: cups

An unknown process (something, most likely some security update in hardy) has converted an adblocking /etc/hosts file from a one ip, one hostname per line format to one ip followed by all hostnames. As a result, gnome desktop logins in hardy failed, and cupsd in intrepid segfaults at startup. Deleting the extremely long line in the hosts file fixed both problems.

added a 500 chars line to /etc/hosts on Jaunty alpha as of 3/20/2009 and I was unable to reproduce the behavior.

[canavan (rainer-ubuntu)]

500 chars isn't very long. Could you please retry with 100k chars or so?

[Carlos J. Hernández (carlos3.14)]

added one 10k line and then one 100k line
  wc /etc/hosts
  25 174 106264

Then restarted jaunty (to rule out desktop login failure) and restarted cups

  sudo /etc/init.d/cups/restart
  * Restarting Common Unix Printing System: cupsd [ OK ]
  sudo /etc/init.d/cup status
  Status of Common Unix Printing System: cupsd is running.

As both restarts succeeded, I can't reproduce the behavior either.

Seems to be fixed in the current CUPS package.
