Description:

I ran unhide on my Arch Linux host today as root and consistently receive this message with unhide -m sys:

WARNING: info.procs changed during test : 64 (was 63)
WARNING: info.procs changed during test : 63 (was 64)

63 and 64 could be any other PID (I assume it's refering to PIDs...) I've seen 128, 129, etc.

To see what was going on I booted from a fresh usb Arch dual iso, updated the repository, and installed unhide from pacman. I got the same results. I still wasn't convinced though so I loaded a re-downloaded iso into Virtualbox (Arch host and guest) and got the same results. This is probably an upstream bug but I thought I would bring it to someone's attention since Google didn't yield many results.

Additional info:
* package version(s)

I tried with my host installation I've been using for a few weeks, up to date with pacman -Syu, as well as freshly-downloaded ISOs, unupgraded.

archlinux-2012.10.06-dualiso.iso
* config and/or log files etc.

rkhunter finds no rootkits, and chkrootkit thinks /sbin/init is infected due to another bug... but that's been confirmed, so no need to elaborate.

Steps to reproduce:

1. Boot up the latest iso however you wish.
2. use wifi-menu to connect (in my case it was WPA)
3. install unhide from pacman after updating the repositories
4. unhide -m sys as root

This task depends upon
