You need to grab a Persistent handle, not a Local one. Local handles are only valid in the current scope, once the current HandleScope unwinds the handle is invalid. In the case of threads, this is what you are running into.
Your problem can be fixed as easily as doing: Persistent<Value> handle = Persistent<Value>::New(local_handle); Where local_handle is whatever you have now. You *must* be sure to call handle.Dispose() on this persistent handle when you're done with it, or it will never garbage collect. Additionally you still must use the Locker API or you will run into access violations, even if your thread is read-only. If you want to actually *copy* the object, that is a little bit more tricky :) On Thu, Apr 11, 2013 at 1:28 AM, Jerry Yin <yinpen...@gmail.com> wrote: > Thanks for your reply.
