Resolved in latest fork. Only took 2 years!

Yes, I ran my code many times again on attempt tests and I could never catch an error.

Hi. Thanks for this detailed presentation. I didn't analyze it deeply, but could this be the same problem as the issue reported by B1ts? Several users reported errors in JS tests. My code (and others, I guess), doesn't seem to be impacted, so it is possible tests need to be seriously reviewed.

This is a non-issue. Please don't raise an issue, if you can't specify the exact problem.

Please say which language you're using and provide a clear example of a bad test when raising an issue, rather that supposing tests are bad without a proof. It is also reasonnable to suppose your code is bad and passes sometimes tests because some cases your code doesn't handle do not always appear in random tests.

You can print whatever you want using console.log.
