can we debug into delete

[George2]

Hello everyone,


I am using Visual Studio 2005 and I am wondering whether we could
debug into the global delete operator?

I have tried to debug by setting a break point to delete statement,
but I could only debug into destructor.

My understanding is, when we call delete, the internal operations are,

1. invoking destructor;
2. invoking global delete operator.

Is my understanding correct?

For example,

class Foo {

int i;

public:

	Foo()
	{
		i = 100;
	}

	~Foo()
	{
		i = 0;
	}
};

int main (int argc, char** argv)
{
	Foo* f = new Foo();

	delete f;  // can not debug inside

	return 0;
}

thanks in advance,
George

Debugging is in general OT in this newsgroup. Debugging under a particalur
platform is even more OT.

I have tried to debug by setting a break point to delete statement,
but I could only debug into destructor.

Almost. If a class has an overwritten delete operator, this particalur
implementation is called (I almost surely used the terms 'operator delete' and
'delete operator' incorrectly here. There is a difference between these terms
that some follow-ups to this posting will explain, but most people can live with
using the terms incorrectly

For example,

class Foo {

int i;

public:

	Foo()
	{
		i = 100;
	}

	~Foo()
	{
		i = 0;
	}
};

int main (int argc, char** argv)
{
	Foo* f = new Foo();

	delete f;  // can not debug inside

	return 0;
}
