Ruby

This simple test program fails with ruby2.3, but worked in previous versions:

require 'tk' require 'tkextlib/tkimg' root = TkRoot.new canvas = TkCanvas.new root canvas.grid :column => 0, :row => 0 img = TkPhotoImage.new :file => "/tmp/l.png" TkcImage.new canvas, 0, 0, :anchor => :nw, :image => img Tk.mainloop 

Backtrace:

/usr/lib/ruby/2.3.0/tk/itemconfig.rb:115:in `hash_kv': wrong argument type nil (expected Array) (TypeError) from /usr/lib/ruby/2.3.0/tk/itemconfig.rb:115:in `itemconfig_hash_kv' from /usr/lib/ruby/2.3.0/tk/canvas.rb:722:in `_parse_create_args' from /usr/lib/ruby/2.3.0/tk/canvas.rb:735:in `create' from /usr/lib/ruby/2.3.0/tk/canvas.rb:758:in `create_self' from /usr/lib/ruby/2.3.0/tk/canvas.rb:751:in `initialize' from ui.rb:8:in `new' from ui.rb:8:in `<main>' 

From what I can tell itemconfig_hash_kv calls tk_hash_kv with args 2 and 3 set to nil, but the new Check_Type introduced in r53077 call does not account for Qnil in there.
