Thanks for the report.  However, I suspect that what happened is that
you have a file in your current working directory whose name starts with
'-', and was therefore treated as an option.  If I'm right, then this
FAQ covers the situation:
https://www.gnu.org/software/coreutils/faq/#I-have-a-file-_0027_002df_0027-and-it-affects-rm_002e

and you can use either of these constructs to avoid the issue:

chown user:user -R ./*
chown user:user -R -- *

For that matter, using '*' with -R is rather pointless; it risks
exceeding command line limits and omits files whose names start with '.'
in the current directory; you probably want to do:

chown -R user:user .

which is also mentioned in the FAQ:
