[Planner Dev] Planner Crashes During Gantt Printing

[John_Minkle huntalternatives org]

The task that causes the crash seems
to be a milestone with no predeccessor.  

In the current source I see.

        /*
FIXME: Remove this check when the scheduler
         *
is fixed. We get a crash here if tasks get
         *
really odd start/finish values. This
         *
sometimes happens for complex projects now.
         */
        if
(!task_coord) {
         
      goto fail;
        }

So I thought is was worth shareing my
finding.

Here is the error from xxgdb.  Note
that my source is from around Jun 11.

Program received signal SIGSEGV, Segmentation

        /*

        if
(gantt_print_get_allocated_resources_string (data, ptask->task, &str,
NULL)) {
         
      task_coord = g_hash_table_lookup (data->task_finish_coords,
         
               
               
        ptask->task);

         
      element = g_new0 (Element, 1);
         
      element->type = RESOURCES;

        ->
       element->x1 = task_coord->x +
data->job->x_pad;
         
      element->y1 = y0 + data->row_height
* (i + 1);

         
      element->resources = str;

         
      page = GET_PAGE (data, row, col - 1);
         
      page->elements = g_list_prepend (page->elements,
element);
        }
 

If I add a predessessor to the mileston,
planner prints the gantt just fine.
