It seems to loop at choose.cc 813.
void
_view::insert_pkg (Package *pkg)
{
pick_line line;
if (pkg->exclude)
return;
line.set_line (pkg);
if (view_mode != VIEW_CATEGORY)
{
if (lines == NULL)
{
lines = (pick_line *) calloc (npackages + ncategories,
sizeof (pick_line));
nlines = 0;
insert_at (0, line);
}
else
insert_under (0, line);
}
else
{
// assert (lines); /* protect against a coding change in future */
for (Category *cat = pkg->category; cat; cat = cat->next)
{
/* insert the package under this category in the list. If this category is not
visible, add it */
int n=0;
while (n < nlines)
{
/* this should be a generic call to list_sort_cmp */
if (lines[n].get_category ()
&& cat->name == lines[n].get_category ()->name)
insert_under (n, line);
n++;
}
if (n == nlines)
{
/* the category wasn't visible - insert at the end */
insert_category (cat, CATEGORY_COLLAPSED);
insert_pkg (pkg); <===============================813
}
}
}
}
Does that mean that pkg = '' ?
Or is it damaged in insert_pkg?

I will aplly it and try to build setup again.
