When developers do make mistakes, it’s often accidental or because the developers are in a hurry. These errors often make their way into small edits to the code. Let’s review one of these cases: a developer fixes an error and introduces a new one simultaneously.

There’s a myth that open-source software is better and safer that the closed one. This was reasonably questioned many times. People regularly find epic vulnerabilities in the open source code. These vulnerabilities have been there for a long time. I think the project quality depends on how the development managers arrange the process and what methodologies/tools are used. It has nothing to do with the project being open source or closed source.

The PVS-Studio developers often check open-source projects and write articles about that. Sometimes, when writing an article, we come across interesting situations or epic errors. Of course, we want to write a small note about it. This is one of those cases.

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.
