Unable to print last line in Linux in while loop

Below is my shell script:

Code:
printf "10\n-rwxr-xr-x 73\n-rwxr-xr-x 74\n10\n-rwxr-xr-x 75\n-rwxr-xr-x 76" |
while IFS=' '
read -r dirn
do
       echo "dirn :"$dirn
done

Output:
Code:
$ ./test.sh
dirn :10
dirn :-rwxr-xr-x 73
dirn :-rwxr-xr-x 74
dirn :10
dirn :-rwxr-xr-x 75

As you can see dirn :-rwxr-xr-x 76 does not get printed.

The exact same code works fine on Aix ksh shell whereas this is bash.

Can you please suggest what is the issue with my code that riun on Linux Redhat bash shell?

NAMEI(1)						      General Commands Manual							  NAMEI(1)

NAME
namei - follow a pathname until a terminal point is found SYNOPSIS
namei [options] pathname... DESCRIPTION
namei uses its arguments as pathnames to any type of Unix file (symlinks, files, directories, and so forth). namei then follows each path- name until an endpoint is found (a file, a directory, a device node, etc). If it finds a symbolic link, it shows the link, and starts fol- lowing it, indenting the output to show the context. This program is useful for finding "too many levels of symbolic links" problems. For each line of output, namei uses the following characters to identify the file type found: f: = the pathname currently being resolved d = directory l = symbolic link (both the link and its contents are output) s = socket b = block device c = character device p = FIFO (named pipe) - = regular file ? = an error of some kind namei prints an informative message when the maximum number of symbolic links this system can have has been exceeded. OPTIONS
-l, --long Use the long listing format (same as -m -o -v). -m, --modes Show the mode bits of each file type in the style of ls(1), for example 'rwxr-xr-x'. -o, --owners Show owner and group name of each file. -n, --nosymlinks Don't follow symlinks. -v, --vertical Vertically align the modes and owners. -x, --mountpoints Show mountpoint directories with a 'D' rather than a 'd'. AUTHOR
The original namei program was written by Roger Southwick <rogers@amadeus.wr.tek.com>. The program was re-written by Karel Zak <kzak@redhat.com>. BUGS
To be discovered. SEE ALSO
ls(1), stat(1) AVAILABILITY
The namei command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. Local NAMEI(1)
