Github Actions workflow Windows 2025/Visual C++ 2022 (test-bundled-gems) has a timeout issue for csv gem.
That timeout seems to have been missed for months.

The following was recorded in a successful test.

Testing the csv gem
  D:/a/ruby/ruby/build/ruby.exe -C D:/a/ruby/ruby/src/gems/src/csv D:/a/ruby/ruby/src/.bundle/bin/rake test
  Sending KILL signal

This should record a failure in the test for the csv gem.

With git bisect, I found the first bad is f30f0f0a22bb5cf536b5ca551f3dfa5ebb745030.
It was also reproduced locally when using the mingw compiler.

But I couldn't discover any more about this issue.

It is another issue that test-bundled-gems.rb correctly recognizes timeouts as failures.
I created a PR14695 for that.
