我正在看到一些奇怪的潜在红宝石2.2.3 gc相关问题,从单词列表生成前缀尝试.可疑代码在这里:

def insert(word)
      return if word.nil? || word.empty?
      node = self
      counter = 0
      l = word.length
      #TODO _ why is this not being garbage collected?
      word.bytes.each do |i|
        counter += 1
        node.children[i] ||= Node.new(i.chr, node, counter == l)
        node = node.children[i]
        node.terminal = true if counter == l
      end
    end

它是从字符串列表中调用的 - 就这样

words.each_with_index do |word, i|
    @root.insert(word)

当我对此进行一些内存分析时,我看到ruby 2.2.3-railsexpress中的总mem用量为~68MB:
