Not a bug - you successfully touched stdout (in this case,
your terminal).  Remember, many commands special case - to
mean stdin or stdout if they operate well on a single file.

ls is not one of those commands.  So rather than listing
stdin or stdout (neither of which makes sense), it tries
to list ./- and fails.

If you really must touch ./-, then say so:

touch ./-
