std.concurrency.receive and shared const(char)[]?

[BakedPineapple]

import std.stdio;
import std.concurrency;

void main()
{
	auto t = spawn((){
		receive((shared const(char)[] char_arr) {
			ownerTid.send(true);
		});
	});
	shared const(char)[] char_arr = "cut my code into pieces";
	t.send(char_arr);
	assert(receiveOnly!(bool) == true);
}

When I run this program, it blocks on the receive() inside the 
spawned thread. What am I doing wrong?
