Bug #3351: stack overflow on super
https://bugs.ruby-lang.org/issues/3351#change-34563

Author: serge_balyuk (Serge Balyuk)
Status: Assigned
Priority: Low
Assignee: shugo (Shugo Maeda)
Category: core
Target version: 2.0.0
ruby -v: ruby 1.9.3dev (2010-05-26 trunk 28028) [i686-linux]


=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.
