Results of online demo don't match results of official cmd utility

Official cmd utility output:

So the result calculated by official utility doesn't match result on website:

official: UJtjJMZRFUqVihDlSt4bjs32FwImLJ1xpdX6Os9mpm/fgt/07jCQzKJxXPAUdKbysgMHZUkEhxIklzDf1IBBog

Steps to reproduce

Download and make from https://github.com/P-H-C/phc-winner-argon2/

Run:

$ ./argon2 somesalt -id -t 30 -m 14 -l 64 <<< "password" > outputfile

EDIT: command line utility reads an 0x0a byte in the end of herestring.

This command outputs matching result:

$ echo -n "password" | ./argon2 somesalt -id -t 30 -m 14 -l 64 > outputfile
