    According to the link in the article, the qsort() bug can only be triggered with a non-transitive cmp() function. Would such a cmp function ever be useful?

      You don’t necessarily have to write a non-transitive cmp() function willingly, it may happen that you write one without realizing due to some edge cases where it’s not transitive.
