Okay, here some info from listnum2listitem() when num < list->low:
Breakpoint 1, listnum2listitem (list=0x80e4ab8, num=700) at list.c:68
68 node = (LISTNODE*)safemalloc(list->items_per_node*list->item_size
(gdb) where

As you can see, we are using article_list. Also, absfirst and
list->low are equal. It looks like something funny is going on with
the NNTP server though. (This is assumming that gdb isn't lying to
me.)
