Description Axel Kollmorgen 2009-07-18 17:23:37 UTC 
the attached files cause doxygen to stop with a segfault. the error happens in this part of scanner.l:

if (current->sli) // copy special list items
{
  QListIterator<ListItemInfo> li(*current->sli);
  ListItemInfo *lii;
  for (li.toFirst();(lii=li.current());++li)
  {
    previous->addSpecialListItem(lii->type,lii->itemId); // <<<< HERE
  }
  delete current->sli;
  current->sli = 0;
}

problem: 'previous' is undefined (in the special case of these files).

quickfix:

-       if (current->sli) // copy special list items
+       if (current->sli && previous) // copy special list items

proper fix: no idea, because i'm not so familiar with doxygen, the scanner, etc. one hint that this needs some more work is the section just above this code, which is '#if 0' outcommented. would be nice if someone with more insight could look over this.

Comment 3 Dimitri van Heesch 2009-07-19 07:45:18 UTC 
Confirmed. Should be fixed in the next subversion update.
Comment 4 Axel Kollmorgen 2009-07-21 00:43:34 UTC 
will you just add the " && previous", or change something in the general processing?
Comment 5 Dimitri van Heesch 2009-08-20 10:13:22 UTC 
This bug was previously marked ASSIGNED, which means it should be fixed in
doxygen version 1.6.0. Please verify if this is indeed the case and reopen the
bug if you think it is not fixed (include any additional information that you
think can be relevant).
