I'm using check_disk (nagios-plugins 1.4.9) 1.91

/usr/local/libexec/nagios/check_disk -c 30% -w 40% -vvvv -p /tmp
For /tmp, used_pct=1 free_pct=99 used_units=2 free_units=4559 
total_units=4958 used_inodes_pct=1 free_inodes_pct=99
Freespace_units result=0
Freespace% result=0
Usedspace_units result=0
Usedspace_percent result=0
Usedinodes_percent result=0
zsh: segmentation fault (core dumped)  
/usr/local/libexec/nagios/check_disk -c 30% -w 40% -vvvv -p /tmp

I can confirm that this plugin works ok with FreeBSD 6.2 (amd64/i386)
-p option work under FreeBSD 7 amd64, but does not under i386 version.
-c is not working on FreeBSD 7 (i386/amd64), but only FreeBSD 6.X

The main differences between FreeBSD 6 and FreeBSD 7 are gcc and libc :)

(6) gcc version 3.4.6 [FreeBSD] 20060305
(7) gcc version 4.2.0 20070514 [FreeBSD]

I'm not sure what is the difference between libc 6 & 7, but all other 
apps that I tested works without a problems.
