Not a bug, but a FAQ:
https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#How-do-I-remove-files-that-start-with-a-dash_003f

Most likely, he is running the command in a directory that contains a
filename starting with a dash, and both 'du -sh -- *' and 'du -sh ./*'
serve to suppress treating that leading dash as an invalid option name.
