error: lifetime may not live long enough
--> $DIR/hr-subtype.rs:54:13

LL | fn supertype<'x, 'y: 'x, 'z: 'y>() {
| -- -- lifetime `'y` defined here

| lifetime `'x` defined here
LL | gimme::<$t1>(None::<$t2>);
| ^^^^^^^^^^^^^^^^^^^^^^^^^ argument requires that `'x` must outlive `'y`
...
LL | / check! { free_x_vs_free_y: (fn(&'x u32),
LL | | fn(&'y u32)) }
| |______________- in this macro invocation
|
= help: consider adding the following bound: `'x: 'y`
= note: this error originates in the macro `check` (in Nightly builds, run with -Z macro-backtrace for more info)
error: aborting due to previous error
