ruby gtk-3上的内存泄露(Memory leak on ruby gtk-3)

 我在使用gtk-3时遇到了ruby 2.3.1的内存泄露问题。 在我的系统上（Ubuntu 16-04），以下代码消耗大约80 MB。 picture.jpg的大小是289kb。 
 
 `require'gtk3' 
 
  def ptest
    i=0
    j=0
    loop {
    i += 1
    j += 1
    exit if j==50
    @image = Gtk::Image.new
    newPixbuf = GdkPixbuf::Pixbuf.new(:file => "picture.jpg")
    @image.pixbuf = newPixbuf
    @image.clear
    @image=nil
    if i == 10
      p "GC"
      GC.start
      i = 0
    end
    }
  end

  ptest`
 
 根据https://sourceforge.net/p/ruby-gnome2/mailman/message/8659687/这应该不会发生。 我能做些什么来释放内存？ 

I'm experiencing a memory leak on ruby 2.3.1 with gtk-3. On my system (Ubuntu 16-04) the following code consumes approximately 80 MB. The size of picture.jpg is 289kb.
 
`require 'gtk3'
 
  def ptest
    i=0
    j=0
    loop {
    i += 1
    j += 1
    exit if j==50
    @image = Gtk::Image.new
    newPixbuf = GdkPixbuf::Pixbuf.new(:file => "picture.jpg")
    @image.pixbuf = newPixbuf
    @image.clear
    @image=nil
    if i == 10
      p "GC"
      GC.start
      i = 0
    end
    }
  end

  ptest`
 
According https://sourceforge.net/p/ruby-gnome2/mailman/message/8659687/ this shouldn't happen. What can I do to release the memory?
