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?

PMKINSTALL(1)						    BSD General Commands Manual 					     PMKINSTALL(1)

NAME
pmkinstall -- install binaries and data SYNOPSIS
pmkinstall [-bcs] [-B suffix] [-g group] [-m mode] [-o owner] file1 file2 pmkinstall [-bcs] [-B suffix] [-g group] [-m mode] [-o owner] file1 ... fileN directory pmkinstall -d [-g group] [-m mode] [-o owner] directory ... pmkinstall -v pmkinstall -h DESCRIPTION
The file(s) are copied to the target file or directory. If the destination is a directory, then the file is copied into directory with its original filename. If the -b option is given and the target file already exists, it is renamed to the original name folloeb by the backup suffix. The default suffix is ".old" but can be overriden with the -B option. The options are as follows: -B suffix Orverride backup suffix -b Backup any existing files before overwriting. -c Copy the file. This is actually the default. The -c option is only included for backwards compatibility. -d Create directories. Missing parent directories are created as required. -g group Specify a group. A numeric GID is allowed. -h Display usage. -m mode Specify an alternate mode. The default mode is set to rwxr-xr-x (0755). The specified mode may be either an octal or symbolic value; see chmod(1) for a description of possible mode values. -o owner Specify an owner. A numeric UID is allowed. -s pmkinstall exec's the command of environment variable STRIP to strip binaries so that install can be portable over a large number of systems and binary types. If the environment variable STRIP is not set, the action is skipped. -h Display version. The pmkinstall utility exits 0 on success, and >0 if an error occurs. ENVIRONMENT
STRIP Set which strip(1) program to run. SEE ALSO
