Hello, The manual says in https://orgmode.org/manual/Internal-Links.html#DOCF25 (footnote 25), that in-buffer completion can be used to insert links targeting a headline in current buffer. So a user can type [[* and C-M-i and all headlines in the buffer are offered for completion.
However, that only works if [[* is the last thing in the line. If there is something after point in that line, it fails with the following message: cl--assertion-failed: Assertion failed: (<= start (point)), #<marker at 243 in foo.org>, 242 Or if there are only whitespaces after point, with the following message instead: pcomplete-completions: Args out of range: "", 1, nil.
