Are these issues reported to LO devs, or they have to look it up themselves?
When checking open-source projects, we almost always report the results to their authors. If we publish such a report as an article, we try to send the link to it to the developers. If there are too few bugs in a project to write an article about, we still report whatever results we've got to the authors. Or rather, we try to - sometimes developers don't (strange as it may sound) have any contacts, or their bug trackers don't accept messages, or you need to enter a captcha which no one can solve.
That's why we never send patches. There are a few reasons for that:
1. We are not familiar with the code and therefore cannot be sure if all the bugs we catch are really bugs. To understand that, we would need to study the project very closely.
2. Even with obvious bugs, we often can't say for sure how to fix them.
3. Finally, we pursue but one goal with our articles - to demonstrate the capabilities of the analyzer we develop. That is, we want to prove that our tool can find bugs in a real-life, living code. We don't aim at fixing bugs - we aim at proving that our tool can find them.
