Most likely, this is not an error in cp, but a misunderstanding on your
part about how globbing operates.  I bet you have a file in your current
directory whose name starts with '-', and is thus being treated as an
option by cp.

No, that's not quite equivalent - it guarantees that the glob won't be
mis-handled as an option.  Likewise,

cp -l -- * DIRECTORY

will avoid treating the glob as an option.  Not only that, but this is a
FAQ:

Sorry, but that's not what you typed.  It helps to show actual examples
when claiming you have a bug.
