Thanks for the report.  However, this is not a bug in dirname, but in
your usage pattern.  You are invoking "dirname -bash", which dirname
(rightly) interprets as the attempt to be the -b option, but dirname
does not have a -b option.  You need to use -- to mark the end of
options and the start of arguments:

dirname -- "$0"

Wow, that's old.  The latest stable version is 8.10.

Wow, that's even older, but same story.
