Hi, thanks for the explanation. I will try again when it is modified based on the final patch.

I just cross-compiled Linux kernel using CodeChecker but I don't get the proper analysis result. I have fixed cross-compilation issue by adding --analyzer-target option to scan-build in http://reviews.llvm.org/D10356.
Could you please explain more about LD_PRELOAD technique? I would like to more understand how it works.

Kind regards,
