I have a situation where I need to know how an object was created
(dynamically or on the stack) and have delete only delete dynamic objects. 
I came up with the following mechanism:

class Base {

public:
   new(...);
   Base(...);
   ~Base();
	  delete(...);

   static int createdDynamically;
		 
			int objectIsDynamic;
};

Base::createdDynamically = 0;

Base::new(...)
{
  Base::createdDynamically  = 1;
	 // do other stuff;
}

Base::Base(...)
{
  this->objectIsDynamic = Base::createdDynamically;
  Base::createdDynamically  = 0;
	 // do other stuff;
}

Base::~Base()
{
  Base::createdDynamically = this->objectIsDynamic;
  // Do other stuff
}

Base::delete(...)
{
  int isDynamic = Base::createdDynamically;
  Base::createdDynamically = 0;
  // do other stuff
}

Assuming single tasking machine.

This scheme should allow me to pass information between new and delete as
long as I am guarenteed that the constructor is called after the new.  I
haven't been able to find any reference to this in ARM so.... Does anyone
know the correct answer?
