It's an internal program running a typical GNU/Linux system. The
program's provenance doesn't matter: it's both legal and possible for
programs to give themselves empty names. Are you suggesting it's okay
for Parallel to fall over and die (in a loop, no less, when executed
with --version) because some program uses a supported API in a way that
displeases you? I hope not, because that attitude would force me to tell
everyone I know to stay away from using GNU Parallel.
