This is broken at least since 2.5 (I didn't check earlier versions). It resulted in failure in test_ast.rb when the tests were added before the parser change. Basically, in remove_duplicate_keys, if the node is modified, set the location information to the previous location information. The removal of keys should not affect the location in the code.
