The fact is all preconditions for "cur != NULL" and "next != NULL" and none of precondtions for "cur != list->tail" are proved automatically. But if I replace "cur != list->tail" by "cur != list->head" then all precondtions for it are proved too. ### Additional Information : Check attach ## Attachments - [sort.c](/uploads/a07fe0acea059a71d361c2ce462cf01d/sort.c)
