Bug #9236

Updated by nobu (Nobuyoshi Nakada) over 10 years ago

=begin 
 The following code behaves differently under Ruby 1 and Ruby 2. 

   

 module Fun 
     
   def hello 
       
     orig_hello 
     end 
   end 

   
 end 

 module M1 
     
   def hello 
       
     p 'hello!' 
     end 
   end 

   
 end 

 module M2 
     
   def hello 
       
     super 
     end 
   end 

   
 end 

 class Foo 
     
   include M1 
     
   include M2 

     

   alias_method :orig_hello, :hello 
     
   include Fun 
   
 end 

   

 Foo.new.hello 


  


 % ruby -v fun.rb 
  
 ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-darwin12.5.0] 
  
 "hello!" 

  

 % ruby -v fun.rb 
  
 ruby 2.1.0dev (2013-12-10 trunk 44126) [x86_64-darwin12.0] 
  
 fun.rb:3: stack level too deep (SystemStackError) 

 Let's see if this is an intended spec change or a bug.
