We invite you to read a new article about how we analyzed another well-known open-source project. This time it is the LibreOffice office suite that I have examined. The project is developed by more than 480 programmers. We have found that it is pretty high-quality and that it is regularly checked by the Coverity static analyzer. But, like in any other large project, we still managed to find previously undetected bugs and defects and in this article we are going to discuss them.
