Instantiating a `type` causes "symbol(s) not found" compilation error

[hraftery]

Describe the bug

Have been happily compiling and testing a lot over the last few days. Just went back to an old source file to try the type feature. I defined type RobotStorage = []string and replaced my existing uses of []string. When I tried to compile I got something like "unknown type in array initialisation" on return [] where previously that had worked to return a []string. So I tried some other options like return RobotStorage{} but when that didn't work just tried return []string{}. At that point the compiler error appeared.

Expected Behavior

Either no errors, or an error about how I'm trying to instantiate a new RobotStorage on line 12.

Current Behavior

% v robot-name.v
==================
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
...
==================
(Use `v -cg` to print the entire error message)

builder error: 
==================
C error. This should never happen.

This is a compiler bug, please report it using `v bug file.v`.

Reproduction Steps

Hmm, I thought this was what v bug robot-name.v was going to do. Um... here's the full file and all I did was run v robot-name.v.

module main

import rand

struct Robot {
mut:
	name string
}
type RobotStorage = []string

fn create_robot_storage() RobotStorage {
	return []string{}
}

fn create_robot(mut robots RobotStorage) Robot {
	n := generate_random_unique_name(robots)
	robots << n
	return Robot { n }
}

fn (mut r Robot) reset(mut robots RobotStorage) {
	n := generate_random_unique_name(robots)
	robots[robots.index(r.name)] = n
	r.name = n
}

fn generate_random_name() string {
	chars  := rand.string(2).to_upper()
	digits := rand.intn(1000) or { panic("Should only happen if 1000 is <= 0")}
	return "${chars}${digits:03}"
}

fn generate_random_unique_name(robots RobotStorage) string {
	for true {
		n := generate_random_name()
		if n !in robots { return n }
	}
	return "" //unreachable, but compiler needs it
}

fn main() {
	println(generate_random_name())
}

Possible Solution

The error message sounds like an installation issue, but I've had no installation issues. So I can only guess it's related to my introduction of type.

Additional Information/Context

I know the importance of this, but I really have nothing more to add - if the exact file and compiler produces the error then that's all the context you need I suppose. If they don't then maybe it's something fleeting.
