To reproduce the bug, run the following command: emacs -Q --eval '(progn (fundamental-mode) (modify-syntax-entry ?/ ". 124b") (modify-syntax-entry ?* ". 23") (modify-syntax-entry ?\n "> b") (setq comment-start "// ") (auto-fill-mode 1) (setq fill-column 9) (setq comment-auto-fill-only-comments t) (insert "/* //x x") (newline))' Expected result: A newline character should be inserted, and point should move to the next line. Actual result: A newline character is inserted, but point is not moved. The *Messages* buffer contains the following message: comment-search-backward: Beginning of buffer The definition of comment-search-backward contains the following possibly relevant comment: ;; FIXME: If a comment-start appears inside a comment, we may erroneously ;; stop there. This can be rather bad in general, but since ;; comment-search-backward is only used to find the comment-column (in ;; comment-set-column) and to find the comment-start string (via ;; comment-beginning) in indent-new-comment-line, it should be harmless.
