A "super" without any argument nor parentheses would pass all given
arguments and a block to the method in the super class.  I think you
wanted to write:

 class C2 < C1
   def initialize( &block )
     super()
     puts "I went here !"
   end
 end

Note empty parentheses after the "super".  

|It's a bug. (or a really surprising feature)

It's a feature, which may be surprising for the newbies.
