In the file debugger/show_information.ml, apply this patch: 25a26 > open Source 72,73c73,78 < fprintf ppf "#%i Pc : %i %s char %i@." < framenum event.ev_pos event.ev_module event.ev_char --- > let first_char_of_line, line = > line_of_pos (get_buffer event.ev_module) event.ev_char in > let char_on_line = event.ev_char - first_char_of_line in > fprintf ppf "#%i Pc : %i %s line: %i char: %i@." > framenum event.ev_pos event.ev_module > line char_on_line Don't forget the "open Source" line, or you won't be able to access the "line_of_pos" function.

It doesn't work for me. When I do this the last location I can see before hitting the exception is about two lines before the location of the bug. I'm having a hard time wrapping my mind around the way the debugger works.
