説明

If a concrete object has properties with abstract values, the interpretation of SerializeJSONProperty in src/intrinsics/ecma262/JSON.js will either fail obscurely or do the wrong thing, such as returning undefined.

It would be better to first check for this case and then go into the JSON.stringify part of the special case code for dealing with JSON.parse(JSON.stringify(abstractObject)).
