Thread: can we debug into delete

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,

Code:

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

You can't "debug" there because you don't have source code to the built-in delete. The debugger will probably allow you to step into it, but you are only going to see machine instructions, not "code."

Why do you want to do this? Hopefully not because your program is crashing inside delete. If that's happening, it means you've corrupted memory somewhere, it DOESN'T mean there's a bug in delete
