[JulienLecoq]

V version: V 0.3.1 d6de533.5e1a2f6
OS: linux, Ubuntu 20.04.3 LTS

What did you do?

module main

fn test(shared values []int) {
	values = [2]
}

fn main() {
	shared values := [3, 3, 3]
	go test(shared values)
}

What did you expect to see?
An error explaining that values = [2] must be surrounded by a lock {} block.

What did you see instead?
V panic: deref: type ast.Type(0x25 = 37) is not a pointer
