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"
