--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I don't see a bug here, it behaves as expected, once you have too long line
somewhere or too many lines, column tracking is disabled and column tracking is
essential for this warning:
  /* PR c++/68819: if the column number is zero, we presumably
     had a location_t > LINE_MAP_MAX_LOCATION_WITH_COLS, and so
     we have no column information.
     Act as if no conversion was possible, triggering the
     error-handling path in the caller.  */
  if (!exploc.column)
    {
      static bool issued_note = false;
      if (!issued_note)
        {
          /* Notify the user the first time this happens.  */
          issued_note = true;
          inform (loc,
                  "%<-Wmisleading-indentation%> is disabled from this point"
                  " onwards, since column-tracking was disabled due to"
                  " the size of the code/headers");
        }
      return false;
    }
This isn't a note that is related to some particular warning, just a message
telling that there won't be any further warnings emitted due to this later.
