[I] [Ruby] Memory behind Arrow::Buffer#data is freed by GC while the Bytes still refer to it [arrow]

himotoyoshi opened a new issue, #54687:
URL: https://github.com/apache/arrow/issues/54687

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   The GLib::Bytes returned by Arrow::Buffer#data reads freed memory once the array is garbage collected, although the Bytes object is still referenced.
   
   ```
   require "arrow"
   
   bytes = Arrow::StringArray.new(["hello world, a long-ish string"]).data_buffer.data
   GC.start
   p bytes.to_s
   # => "\x80\x00_AN\x02\x00\x00rld, a long-ish string"
   ```
   
   Environment: red-arrow 25.0.1, apache-arrow-glib 25.0.1 (Homebrew), Ruby 3.4.1, macOS 15.4.1 (arm64)
   
   ### Component(s)
   
   Ruby
