[ruby-core:46968] [ruby-trunk - Bug #3351][Open] stack overflow on super

Issue #3351 has been updated by shugo (Shugo Maeda).

Status changed from Closed to Open

In HEAD of trunk, stack overflow doesn't occur, but Override#foo is called only once.
So I reopen this ticket.

Bug #3351: stack overflow on super

=begin
 It looks like `super` behavior is a bit different in 1.8 and 1.9. Please find the example below:
 
 class Base
   def foo
     puts "bar"
   end
 end
 
 module Override
   def foo
     puts "override"
     super
   end
 end
 
 
 class A < Base
 end
 
 class B < A
 end
 
 B.send(:include, Override)
 A.send(:include, Override)
 
 B.new.foo
 
 ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux] output:
 
 
 override
 override
 bar
 
 
 and ruby 1.9.3dev (2010-05-26 trunk 28028) [i686-linux] output:
 
 ....
 override
 override
 override
 override
 override
 super.rb:9: stack level too deep (SystemStackError)
 
 
 Hope that helps.
