Please write in English if possible, because the Emacs maintainers usually do not have translators to read other languages for them. Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list, and to the gnu.emacs.bug news group. Please describe exactly what actions triggered the bug and the precise symptoms of the bug: if I compile the following with ocamlc: let foo : int = "foo" ^ "bar" it gives me the error File "/home/palomer/temp/test.ml", line 2, characters 1-21: ... which refers to: "foo" ^ "bar" next-error will try and highlight characters 1 to 21 on line 2. however, line 2 only contains 10 or so characters. This is because character 21 actually refers to character 8 on line 4. Instead of highlighting 3 lines, only 1 line is highlighted. If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'. If you would like to further debug the crash, please read the file /usr/share/emacs/22.2/etc/DEBUG for instructions.
