Description
I tried this code:
```
fn much_larger_type(default: Default) -> MuchLargerType<Default> {
// implementation elided
}
fn box_new<T>(t: T) -> Box<T> {
// implementation elided
}
fn tuple_with_one_element<T>(t: T) -> (Box<T>, usize) {
// implementation elided
}
fn closure_that_prints_stuff<T>(t: T) -> () {
let p = t.0.0;
println!("{} {:?}", t.1, p);
}
fn main() {}
```
I expected to see this happen: compilation success
Instead, this happened: ICE
