cppcheck / Discussion / General Discussion: Error after using latest addons folder

Hello,
I was using cppcheck 1.90 and copied the latest addons folder from github and am getting the following errors on 2 files:

Hello, Amir,

Do these errors occur only on certain files?

It like the addon can't properly parse the raw tokens for the array definition. Could you please provide some minimal code examples?

Hello,
I just did a pull on main and I'm still getting the crash on mcalUart.c:

I've attached the dump file and mcalUart.c for you.

  I can't reproduce this with the dump file generated for your source with cppcheck from the main branch (commit b472b4e65da579ea00475f13be4daf5b28259c36).
  
  But misra_9.py script fails on dump from your attachment. I'm not sure how did you get this dump, because it's very different from the mine. The size of my dump is about 30% less then yours. I'm not sure how can I reproduce this, so I can't reduce this problem to a single unit test.
  
  Could you please update your cppcheck installation? I think this will solve the problem.

Hi Georgiy,

We've been trying to resolve this issue and looks like we're close. We were using cppcheck 1.9 before which was the initial issue. We've updated to 2.3 and noticed our install of python was being corrupted. I then reinstalled python (3.8.5) and now am getting the following error:

Hi, Amir,

I can't reproduce this error with latest master (0338e99f84bceaab75cf9dd321d3e85a2935b0d3). Everything works correctly.

Please, verify your Cppcheck installation.

To make sure that Cppcheck actually works, you can try call it from this docker container: https://hub.docker.com/r/jubnzv1/cppcheck . This is the latest version which updates automatically through github actions: https://github.com/jubnzv/cppcheck-docker .

it looks like the addons folder wasn't replaced when I did the install of cppcheck 2.3. I uninstalled, and deleted the folder in program files and that resolved the issue.

Thank you,
Amir
