Compiler crash if struct contains optional empty struct

const std = @import("std");

const NoteParams = struct {};

const Container = struct {
    params: ?NoteParams,
};

pub fn main() void {
    var ctr = Container {
        .params = NoteParams {},
    };
}

Compiler crashes at a random point (or maybe it's just an artifact of the progress thing). Example outputs from three attempts:
