An essential part of any modern static code analyzer is data flow analysis. However, from an outside perspective, the use of data flow analysis and its benefit is unclear.

Why PVS-Studio Uses Data Flow Analysis: Based on Gripping Error in Open Asset Import Library

by Andrey Karpov

From the article:

It all started with checking the latest version of the Qt 6 library. There was a separate usual article on this, where I'd described 77 errors found. It turned out that at first, I decided to flip through the report, not excluding the third-party libraries' warnings. In other words, I didn't exclude the warnings related to \src\3rdparty in the settings. It so happened that I immediately ran up against a gripping error example in the Open Asset Import Library. So, I decided to write this extra little note about it.
