Description
Minimal Test Example:
struct Cell<T> {
value: T,
}
fn main() {
let Cell{ value: _ } = 0u;
}Rust first complains about mismatched types (expected uint but found a structure pattern). It then throws an ICE (internal compiler error: Type parameter T out of range when substituting (root type=T)).
