New issue 1215 by erights: "name" and "message" have bad attributes on
*Error.prototype
http://code.google.com/p/v8/issues/detail?id=1215

On Error.prototype itself, "message" is enumerable when it shouldn't be.

For all so-called NativeError.prototype objects, they inherit
their "message" property from Error.prototype rather than having their own.
I have no idea why the spec mandates otherwise; as it seems perfectly
sensible to me to inherit this. But the spec is the spec.

For Error and all NativeError.prototype objects, "name" is {writable:
false, enumerable: true, and configurable: false} when all of these should
be the opposite. Unlike
https://bugzilla.mozilla.org/show_bug.cgi?id=637207
this initial mis-configuration also prevents an initialization script from
fixing this, as demonstrated:

d8> Object.defineProperty(Error.prototype, 'name', {writable: true,
enumerable: false, configurable: true})
(d8):1: TypeError: Cannot redefine property: defineProperty
Object.defineProperty(Error.prototype, 'name', {writable: true, enumerable:
fa

I will take a look and make sure we follow webkit (although judging from
your webkit bug they are not standard compliant either)

From my testing, it looks like this bug can be closed as Fixed. Btw, the
WebKit and Mozilla bugs cited above are also now closed as fixed.

Related to issue 1595 , which is a distinct issue.
