Please see the following code. I want to add a JS Date to a Object
available in the global object. This works with a older version
(4.9.385.28) but fails with (5.0.71.33)... see output
g++ -I/usr/local core.c -o testCore -ldl -pthread -std=c++0x -lv8
-lv8_libplatform -lv8_libbase
core.c:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "include/libplatform/libplatform.h"
#include "include/v8.h"

using namespace v8;
class ArrayBufferAllocator : public v8::ArrayBuffer::Allocator
{
public:
virtual void* Allocate(size_t length) { void* data =
AllocateUninitialized(length); return data == NULL ? data : memset(data, 0,
length); }
virtual void* AllocateUninitialized(size_t length) { return malloc(length);
}
virtual void Free(void* data, size_t) { free(data); }
};
int main(int argc, char* argv[])
{
// Initialize V8.
V8::InitializeICU();
V8::InitializeExternalStartupData(argv[0]);
Platform* platform = platform::CreateDefaultPlatform();
V8::InitializePlatform(platform);
V8::Initialize();
// Create a new Isolate and make it the current one.
ArrayBufferAllocator allocator;
Isolate::CreateParams create_params;
create_params.array_buffer_allocator = &allocator;
Isolate* isolate = Isolate::New(create_params);
Isolate::Scope isolate_scope(isolate);
// Create a stack-allocated handle scope.
HandleScope handle_scope(isolate);
Local<Context> context =
Context::New(isolate,NULL,ObjectTemplate::New(isolate));
Context::Scope context_scope(context);
Local<ObjectTemplate> activity = ObjectTemplate::New(isolate);
