The check copyright years CI script is considering main.c a new file, hence the failure.

@kgryte was the cppcheck update necessary?

[kgryte]

According to @Planeshifter, yes, as GitHub actions updated and cppcheck could no longer compile. We thus migrated to the latest version, but the linting rules have updated and we're playing catch-up. 😬

[kgryte]

@headlessNode I am not sure how we'd satisfy the current lint warning. Ideas?

[kgryte]

If there isn't an easy workaround/fix, we could also suppress the lint rule for the offending line(s).

[headlessNode]

@kgryte not sure. Using malloc would be unnecessary. I think suppressing the rule seems reasonable in this case.

[kgryte]

@headlessNode Seems fine with me. At some point, we do need to refactor benchmarks to use malloc, but that can be saved for another day.

[headlessNode]

@kgryte That could be a nice set of good first issues.

[kgryte]

Thanks for working on this @headlessNode. Left an initial round of comments.

[headlessNode]

@kgryte changes applied. The test failure from a downstream test suite.

[kgryte]

LGTM. Thanks, @headlessNode!

[kgryte]

As mentioned in #3083 (comment), the test failure in the downstream library is expected and will be resolved in a subsequent PR/commit. As such, I'll go ahead and merge.
