2025-11-01T14:47:39+00:00

The following script leaks memory:

      100_000.times do
        "\ufffd".encode(Encoding::US_ASCII, fallback: proc { Object.new })
      rescue
      end

      puts `ps -o rss= -p #{$$}`
    end

Add a custom error class to TestString#test_encode_fallback_raise_memory_leak

2025-10-28T23:40:25+00:00

This prevents a generic RuntimeError from being raised so we can ensure
that the correct error is being rescued.

The method and aref cases need to accept a parameter.
