In this article, we invite you to try to find a bug in a very simple function from the GNU Midnight Commander project. Why? For no particular reason. Just for fun. Well, okay, it's a lie. We actually wanted to show you yet another bug that a human reviewer has a hard time finding and the static code analyzer PVS-Studio can catch without effort.

Just about the fastest portable 64-bit hash function with decent quality.

This is a translation of the original article by Leonid Yuriev.

At the beginning of 2018 our blog was complemented with a series of articles on the sixth check of the source code of the Chromium project. The series includes 8 articles on errors and recommendations for their prevention. Two articles sparked heated discussion, and l still occasionally get comments by mail about topics covered in them. Perhaps, I should give additional explanations and as they say, set the record straight.
