Unexpected 2.3.2 spew

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'   <snip>

Here is the relevant code to duplicate. The interesting thing is, just the existance of the empty self.inherited(c) 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(c)   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
