Sorry, I indeed switched to a wrong browser tab and skimmed instead of reading when started this discussion. Please disregard the quicksort discussion.

I still think that it's normal for programs to behave weird when the input parameters are getting close to INT_MAX. Sometimes it's unavoidable. And if it's not specified in the function docs, you should go and check the implementation as a programmer. For binary search it is avoidable, so the criticism of the linked implementation is fair.
