Can you name an older version of cppcheck which is working well?

I don't have an answer for this yet, I've run into unrelated issues trying to get cppcheck 2.16.0 working with CodeChecker. Will report back when I have an answer.

It seems that Cppcheck 2.16.2 works fine with CodeChecker

I changed the following to make it work. I am not aware of the consequences.

Can confirm, after applying this patch, cppcheck was able to run successfully.
