Please take a look at the following code:
static void
label_sort_with_costsize(PlannerInfo *root, Sort *plan, double limit_tuples)
{
...
    cost_sort(&sort_path, root, NIL,
              lefttree->total_cost,
              plan->plan.disabled_nodes,
              lefttree->plan_rows,
              lefttree->plan_width,
              0.0,
              work_mem,
              limit_tuples);

Given the cost_sort() declaration:
void
cost_sort(Path *path, PlannerInfo *root,
          List *pathkeys, int input_disabled_nodes,
          Cost input_cost, double tuples, int width,
          Cost comparison_cost, int sort_mem,
          double limit_tuples)

Aren't the input_disabled_nodes and input_cost arguments swapped in the
above call?

(I've discovered this with UBSan, which complained
createplan.c:5457:6: runtime error: 4.40465e+09 is outside the range of 
representable values of type 'int'
while executing a query with a large estimated cost.)

Best regards,
Alexander
