This error + causes an interesting situation with the pre-collected single-linked + list of states to be splitted: many items were added to the list, but + only several of them are accessible from the list beginning, + since the "tmp" member of struct state (which is used here to + hold a pointer to the next list item) gets overwritten, which + results in a "looped" chain. As a result, not all of states are + splitted, and one state is splitted two times, causing incorrect + "no-progress" flag values. 2003-11-16 Donal K. Fellows -- cgit v0.12
