Static code analysis allows you to identify and eliminate many defects at an early stage. Moreover, it's possible to detect dormant errors that don't show themselves when they appear. They can cause many problems in the future and it requires many hours of debugging to detect them. Let's look at an example of such a dormant error.
To show the advantage of regular use of the PVS-Studio static analyzer, we regularly check the Blender project. My colleague wrote more about this idea here.
