Invalid Memory Allocation

[Cesar Valdez]

Hi All,

I working in a add-on for Node.js, and i have the following problem:

class A {

  local<object> CreateObject( callback) {
   
     if(!p->isEmpty()){
      auto tmp = Object::New(Isolate, objTemplate); //get from cache.
      return tmp->newInstance();  //we have a template, create a instance.
     }
   
      /* create object here and assign callback  {x:callback[function]}  */
      objTemplate.Reset(Isolate, obj);  //cache here.
      return obj->newInstance();.
   }

  ~A(){
    objTemplate.Reset();  
  }

 private:
  Persistent<ObjectTemplate> objTemplate;
}

/* NativeFunction declared here will be linked to obj methods created by A */

A a;
void MakeObject(functionCallbackInfo args){
   args->GetReturn().Set(a.CreateObject(NativeFunction))

}

Javascript

Enter code here...

(function(){

  for(var i=0; i<1000; i++) {
  
   // this call MakeObject in C++.
   var tmp = make_object();            // tmp => {n:[function],....};
  }

})

I just want to cache the Object members using a template, cause i find that it was way slower to make the object from scratch, problem is that when the VM finish i got a SIGSEGV Segmentation fault,
I'm assume this is because of GC, so I add the cleaning function in the desctructor but not luck, the only way to avoid the SIGSEGV is to delete the object way before exit.

I'm thinking to use Eternal<>, but just wanted to know if this is not a good use case for Persistent?  Is a more elegant way to solve this problem ? or I'm doing something wrong.

Thanks.
