Problems with GetKeysInFixedArrayFor function

[G B]

I've been working on a project built upon V8 and I tried to write

C++ versions of Seal() and isSealed() functions you can use with the API.

I've managed to develop a solution and it works fine except when the

object that I want to be sealed has an interceptor returning back

anything but the empty value (Handle<Value>()). I wrote a simplified

version of the code that emphasizes the core of my problem. I attached it

to this mail (v8_test.patch) along with a source for testing it (v8_test.cpp).

The static method Object::Test() works as follows: It takes an object,

gets its properties and sets them into a newly created object. It seems

to me that the GetKeysInFixedArrayFor() function behaves strangely in

this snippet. If you call the Object::Test() method the printf statements

(after the for-loop that sets the properties) work as expected - printing

the number of local properties - but when there is an interceptor that

returns any non-empty value they print out zeroes. I checked the properties

with the HasOwnProperty() method in another piece of code and they were there.

My questions are: 

 - Is this the way the GetKeysInFixedArrayFor() function is supposed to work?

 - If that is so how am I to evade that limitation?
