I don't know. But I know that my little trick doesn't work in 
lifetime.d although it works locally. Here what I tried:

----
import std.stdio;

struct Foo {
	int id;
}

void main() {
	Foo[] fs;
	fs ~= Foo(45);
	fs ~= Foo(46);
	fs ~= Foo(47);
	fs ~= Foo(48);

	auto ti = typeid(fs);
	writeln("&ti = ", &ti);

	void* p = fs.ptr;

	void[] arr = *cast(void[]*) p;

	void* tp = cast(void*)((&arr) - cast(void*) 8);

	TypeInfo ti2 = *cast(TypeInfo*) tp;
	writeln(ti, " versus ", ti2);
}
----

Since rt_finalize and the GC have the same pointer as 'fs.ptr' I 
cast it to an array struct. From the pointer of this struct I 
subtract 8 (8 because of try and error until the pointer was 
equal the real TypeInfo pointer). This I can cast to the 
TypeInfo: it works. But not in lifetime.d. Was a try, but I have 
no idea why it doesn't work (the pointers aren't equal). An idea 
or alternative?
