#239 new defect

Including kernel but not threads crashes vtable generation

Description

This code crashes the compiler:

#include <kernel.hfa>

thread test {};
void ?{}(test & this) {}
void ^?{}(test & mutex this) {}
void main(test & this) {}

int main() {
	test t;
}

It's something to do with vtables:
