Persistent<Function> f, gets initialized to garbage value when allocated using new.

Hi,

I am developing an addon for node.js using V8. 

I have a C structure enclosing Persistent<Function>.  https://github.com/aerospike/aerospike-client-nodejs/blob/master/src/main/client/get.cc.

I allocate this C structure using `new`. When I compile the addon in Release mode, the val_ structure inside Persistent<Function> is initialized to NULL. When I compile the addon in debug mode, 

the same val_ structure is initialized to garbage value. Subsequently, I try to assign a Local<Function> to this Persistent<Function>, the V8 code tries to free up the existing val_, which is some garbage. 

This crashes the addon module in debug mode. I would like understand the difference in behavior for release and debug mode compilation. And the reason behind val_ getting initialized to garbage value.

Thanks
