Yes the differences in the expected results in these four test cases are caused by differences in error messages between V8 and JSC.

The error message regarding serializing cyclic structures in JSC is "JSON.stringify cannot serialize cyclic structures." (Source/JavaScriptCore/runtime/JSONObject.cpp line 412) while the comparable error message in V8 is "Converting circular structure to JSON" (v8/src/messages.js line 116).

V8 prepends the string "Uncaught " (v8/src/messages.js line 55) to uncaught exceptions whereas JSC does not.
