I think I've encounter the same error with the following code: fn main() {
enum List {
Cons(int, ~List),

Cons(b, ~Nil) => (),
_ => ()
}

@daimrod that's possibly slightly different (at least, the failure message is different, although they're in the same area of code). Btw, the MCE still works when used without unique vectors: fn main() {
match &[] {
[] => (),
[2, ..] => (),
[3, 4, ..] => ()
}
}
