Description:

The upgrade to iputils 20121011-1 seems to have broken ping -f in a really bad way.
It does not send echos. It hangs. It does not respond to interrupts. And hanged instances max out one core of the CPU per hanged instance.

I use ping -f on cron jobs that run every 5 minutes to check connectivity. And that caused overheat and full freeze and I had to force restart eventually.

Additional info:
* package version(s)

Broke: 20121011-1
Working: 20101006-7

Steps to reproduce:

ping -f -i .2 google.com

Multiple users in IRC confirmed the bug for both arches.
This task depends upon
