error[E0506]: cannot assign to `*s` because it is borrowed
--> $DIR/guarantor-issue-46974.rs:7:5

LL | let t = &mut *s; // this borrow should last for the entire function
| ------- `*s` is borrowed here
LL | let x = &t.0;
LL | *s = (2,);
| ^^^^^^^^^ `*s` is assigned to here but it was already borrowed
LL | *x

error: lifetime may not live long enough

LL | fn bar(s: &Box<(i32,)>) -> &'static i32 {

LL | // FIXME(#46983): error message should be better
LL | &s.0
| ^^^^ returning this value requires that `'1` must outlive `'static`
error: aborting due to 2 previous errors
