#![feature(generators)]
// Test for issue #47189. Here, both `s` and `t` are live for the
// generator's lifetime, but within the generator they have distinct
// lifetimes. We accept this code -- even though the borrow extends
// over a yield -- because the data that is borrowed (`*x`) is not
// stored on the stack.
// check-pass
fn foo(x: &mut u32) {
move || {
let s = &mut *x;
yield;
*s += 1;
let t = &mut *x;
yield;
*t += 1;
};
}
fn main() {
foo(&mut 0);
}
