TGE's memory management

For a reason, I have to disable the TGE's memory management: using TORQUE_DISABLE_MEMORY_MANAGER.

After building the executable, the program fault at the following with "<<<<<"

while(mNotifyList)
   {
      Notify *note = mNotifyList;
      mNotifyList = note->next;
      
      AssertFatal(note->type != Notify::ClearNotify, "Clear notes should be all gone.");
      
      if(note->type == Notify::DeleteNotify)
      {
         SimObject *obj = (SimObject *) note->ptr;
         Notify *cnote = obj->removeNotify((void *)this, Notify::ClearNotify);
         obj->onDeleteNotify(this);
         freeNotify(cnote);
      }
      else
      {
         // it must be an object ref - a pointer refs this object
         [b]*((SimObject **) note->ptr) = NULL; <<<<<<<<[/b]
      }
      freeNotify(note);
   }

It is the notification list of ParticleData. The notification is registered by:

void ParticleData::initializeParticle(Particle* init, const Point3F& inheritVelocity)
{
   init->dataBlock = this;  <<<<<<<

   // Calculate the constant accleration...
   init->vel += inheritVelocity * inheritedVelFactor;
   init->acc  = init->vel * constantAcceleration;

However, there is no init->dataBlock = 0 to unregister it while removing.

void ParticleEmitter::advanceTime(F32 dt)
{
   Parent::advanceTime(dt);

   mElapsedTimeMS += (S32)(dt * 1000.0f);

   U32 numMSToUpdate = (U32)(dt * 1000.0f);
   if (numMSToUpdate == 0)
      return;

   Particle** ppProbe = &mParticleListHead;
   while (*ppProbe != NULL) {
      (*ppProbe)->currentAge += numMSToUpdate;
      if ((*ppProbe)->currentAge >= (*ppProbe)->totalLifetime) {
         // Remove this particle
         Particle* remove   = *ppProbe;
		 [b]remove->dataBlock = 0;  <<<<< ADDED <<<<<[/b]
         *ppProbe           = remove->nextInList;
         remove->nextInList = NULL;
         sgParticleEngine->releaseParticle(remove);
      } else {
         ppProbe = &((*ppProbe)->nextInList);
      }
   }

It is no problem if using TGE's memory management. Should I have to change lot of codes if I need to disable the TGE's MM?
