Представленный код выполняется много раз и работает с одним экземпляром переменной (g_creator, g_isolate).При втором вызове этого кода возникает исключение в функции v8 :: Context :: New.Что может быть причиной ошибки?
v8::StartupData blob;
v8::SnapshotCreator* creator = NULL;
v8::Isolate* isolate = NULL;
if (g_creator && g_isolate)
{
creator = g_creator;
isolate = g_isolate;
}
else
{
blob.data = (const char*)snapshot.data();
blob.raw_size = snapshot.size();
creator = new v8::SnapshotCreator(NULL, &blob);
isolate = creator->GetIsolate();
g_creator = creator;
g_isolate = isolate;
}

v8::HandleScope handle_scope(isolate);
v8::TryCatch try_catch(isolate);
v8::Local<v8::ObjectTemplate> global = v8::ObjectTemplate::New(isolate);
