Even though the commit ff46dad has shortened the map code, I found that it may be incorrect because the second parameter passed to the function
rb_set_parent
on line 537 is*indirect
, which was just assigned to the value of new node in the previous statement. I added a variableparent
to store the previous value ofindirect
before any changes were made and set it as the parent ofnew_node
as the old code intended.
