Hi,
We are in the final stages of refining a new static analysis framework and
are testing it out on various large open source software projects (like
other ventures in this space).
Unlike other enterprises, we are making a linux intraprocedural analysis
tool openly available in binary form to allow our results to be reproduced
and validated. Ditto the bug lists.
Although this is commercial software, our team are all strong OS advocates
and contributors. We hope to release some components of this project on an
OS basis just as soon as we can trash out a solid plan which allows this
while also enabling us to purchase food.
I've only attached 1 or 2 bugs at the end here (the full list is about 10K
ascii text), there are at www.cqsat.com/linux.html#bugs. There's about 50
and I recon 20 or so are both real and not yet identified.
Any comments/issues/feedback is appreciated.
