hmm strange my svn version claims to be
$ ./check_disk -V
check_disk v1848 (nagios-plugins 1.4.11)

Handling between -p and -A slightly differs. So as a first shot,I'd 
suspect gnulib (mountlist.c) to be the cause. What's your OS platform?

i tested on my laptop:
./check_disk -w 50 -c 10 -A
DISK OK - free space: / 36028 MB (80% inode=96%); /var/run 505 MB (99% ...
/data/home/mga/phlog=8523MB;46886;46926;0;46936

and df:
thisis.a.veryveryverylong.hostname.and.domain:/home/mga/phlog/
                        46G  8.4G   36G  20% /data/home/mga/phlog

without problems.

in this case all by mountlist reported partitions are checked.

here, your path is checked but path output comes from mountlist. But 
free space is too large, though..

Please send some output of running these checks using -vvvv
this might help.
