Compile this file with the x64 MC compiler:

// testcpp.cpp
class ClassDeclaration
{
};

extern ClassDeclaration* ti2;

class Type
{
public:
	static ClassDeclaration* typeinfovector;
};

ClassDeclaration* foo()
{
	return ti2 ? ti2 : Type::typeinfovector;
}

and link with

// test.d
extern(C++) class ClassDeclaration
{
}

extern(C++) class Type
{
	static __gshared ClassDeclaration typeinfovector;
}

extern(C++) __gshared ClassDeclaration ti2;

extern(C++) ClassDeclaration* foo();

void main()
{
    foo();
}
