==============
import core.stdc.stdio;

version(D_BetterC) {
	extern(C) void main() {
		start;
	}
} else {
	void main(){
		start;
	}
}

struct Proxy {
	this(bool i){}
	
	~this() {
		printf("~this(%x)\n", &this) ;
	}
	void opAssign(Proxy other){
		printf("opAssign(this=%x), other=%x\n", &this, &other) ;
	}
}

Proxy proxy;

void start(){
	proxy = getProxy();
}

ref auto getProxy(){
	auto proxy	= Proxy(1);
	return proxy ;
}

version(D_BetterC) extern(C) {
	__gshared int _d_eh_personality(int, int, size_t, void*, void*) 
{ return 0;};
	__gshared void _d_eh_resume_unwind(void*) { return ;};
}
