For many years, Andrey Karpov has been publishing articles on code quality, and bugs reviews of open source projects. For example, he is the author of such publications as “The Ultimate Question of Programming, Refactoring, and Everything” and “27 000 Errors in the Tizen Operating System“.
Recently, the open source Android operating system has become of interest for him. He researched that part of the operating system code, which is written in the C and C++ languages. After that he came to a conclusion, which always takes place after such research: human error is always possible. By using the PVS-Studio tool, it becomes possible to detect at least one security defect (potential vulnerability) per 4000 lines of code.
