Subject: Strange crash (interpreter bug?)

I was trying to fix the busy_handler of the sqlite3. (version 1.1.0 makes 
the interpreter crash)

Rewriting busy_handler in lib/sqlite3/native/driver.rb from

    def busy_handler( db, data=nil, &block )
      if block
        cb = API::CallbackData.new
        cb.proc = block
        cb.data = data
      end

      API.sqlite3_busy_handler( db,
        block ? API::Sqlite3_ruby_busy_handler : nil, cb )
    end


to

    def busy_handler( db, data=nil, &block )
      if block
        cb = API::CallbackData.new
        cb.proc = block
        cb.data = data
        API.sqlite3_busy_handler( db, API::Sqlite3_ruby_busy_handler, cb)
      else
        API.sqlite3_busy_handler( db, nil, nil)
      end
    end

fixed the problem (at least on my system)

For me, those two functions are strictly equivalent. So ... where's the 
difference ?
