//~^^^^^^ ERROR cycle detected when computing layout of `Foo`

// If the inner `Foo` is named through an associated type,
// the "infinite size" error does not occur.
struct Foo(<&'static Foo as ::core::ops::Deref>::Target);
// But Rust will be unable to know whether `Foo` is sized or not,
// and it will infinitely recurse somewhere trying to figure out the
// size of this pointer (is my guess):
const _: *const Foo = 0 as _;
//~^ ERROR it is undefined behavior to use this value
