Can dmd compile with my own runtime library?

I solved this problem by defining a function like below:
void _D11TypeInfo_Aa6__initZ()
{
	while(1){}
}
But it is stupid to do such a thing.

Now my object.d can be linked well. 
And I want to know how the classinfos get the information of the class, is it stored in a initialized data section?

I wrote this program with my object.d

class A{
	private int a;
	this()
	{
		a = 0x00111111;
	}
	~this()
	{
		a= 0x88111111;
	}
}
class B : A
{
	private int b;
	this()
	{
		b = 0x00222222;
		super();
	}
	int printok()
	{
		b = 0x00333333;
		return b;
	}
	~this()
	{
		b = 0x88222222;
	}
}
extern (C) int test()
{
	B b = new B;
	b.printok();
	delete b;
	return 2;
}

The result is 
test(): passed
a.this(): passed
b.this(): passed
b.printok() : passed
b.~this(): not passed
a.~this(): not passed

I don't know why the two disconstructors are not passed everytime. When I check the deallocator of the classinfo of these two classes, they are all empty pointers. 

This is my _d_delclass:

	void _d_delclass(Object *p)
	{
		if (*p)
		{
		//debug (PRINTF) printf("_d_delclass(%p)\n", *p);

		ClassInfo **pc = cast(ClassInfo **)*p;
		if (*pc)
		{
		ClassInfo c = **pc;

		if (c.deallocator) //====failed at here!!!!!!!!! 
		{
			_d_callfinalizer(cast(void *)(*p));
			fp_t fp = cast(fp_t)c.deallocator;
			(*fp)(*p);			// call deallocator
			*p = null;
			return;
		}
		}
		free(cast(void*)(*p)); //passed.
		*p = null;
		}
	}
