// 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
|
