According to [1]
As of the current version 1.0.8, bzip2 --version will print version
info but it will also continue compressing stdin:
$ ./bzip2 --version
bzip2, a block-sorting file compressor. Version 1.0.8, 13-Jul-2019.
Copyright (C) 1996-2019 by Julian Seward.
This program is free software; [...]
bzip2: I won't write compressed data to a terminal.
bzip2: For help, type: `bzip2 --help'.
This is a long-standing bug, not new to 1.0.8 -- the same code
(license() followed by break, with no exit) exists in bzip2 1.0.6 and
earlier. The upstream bzip2 master branch on GitLab already includes
this fix.
Debian (and its downstreams like Ubuntu) will patch this out [2],
making the < /dev/null unnecessary, port a part of debian patch
to fix the issue
