Suspicious code fragments

Hello!

I checked your project (the code corresponds to this [version](https://github.com/dotnet/runtime/tree/v10.0.8)) using a static analyzer. It detected some notable code fragments that I described in an [article](https://pvs-studio.com/en/blog/posts/csharp/1380/), and you might want to take a look at them.

Please note that the article includes only the most interesting warnings. If you wish, you can check the project yourself using the [free version of the analyzer for open-source solutions](https://pvs-studio.com/en/order/open-source-license/) or the [trial version](https://pvs-studio.com/en/pvs-studio/try-free/).
