A 2.3.2 test case that spews:

/home/adam/ror/2.3.2/vendor/rails/activerecord/lib/active\_record/base.rb:2189:in  
`dup': can't dup NilClass (TypeError) from /home/adam/ror/2.3.2/vendor/rails/activerecord/lib/active_record/base.rb:2189:in`scoped\_methods’  
from  
/home/adam/ror/2.3.2/vendor/rails/activerecord/lib/active\_record/base.rb:2193:in  
`current_scoped_methods' from /home/adam/ror/2.3.2/vendor/rails/activerecord/lib/active_record/base.rb:2183:in`scope’  
from  
/home/adam/ror/2.3.2/vendor/rails/activerecord/lib/active\_record/base.rb:2414:in  
`set_readonly_option!' from /home/adam/ror/2.3.2/vendor/rails/activerecord/lib/active_record/base.rb:610:in`find’  
from /home/adam/ror/2.3.2/lib/test1.rb:9:in `initialize\_test’

Here is the relevant code to duplicate. The interesting thing is, just  
the existance of the empty self.inherited© declaration triggers the  
spew. Remove the declaration and no spew. Also, this works fine in 2.2.2  
(no spew).

Create a fresh 2.3.2, and script/console this:

class Y \< ActiveRecord::Base  
def self.inherited©  
end  
end  
class T \< Y  
end  
T.find(:all) # Unexpected spew

You are overwriting the inherited method from ActiveRecord::Base with  
your own but without calling the existing implementation
