Before, this could lead to confusion due to JS_IsExceptionPending usage and the like. Now it will lead to odd failure due to immediate rethrow on js_Interpret reentry (e.g., from eval). See bug 341821. ECMA-262 Edition 3 12.14 semantics for the second production are clear. We need to save the result of evaluating the try block while evaluating the finally, and propagate that result if the finally completes normally (not abruptly, e.g. by throwing or returning). /be
