// This is similar to two-phase-reservation-sharing-interference.rs
|
|
// in that it shows a reservation that overlaps with a shared borrow.

|
|
// Currently, this test fails with lexical lifetimes, but succeeds
|
|
// with non-lexical lifetimes. (The reason is because the activation
|
|
// of the mutable borrow ends up overlapping with a lexically-scoped
|
|
// shared borrow; but a non-lexical shared borrow can end before the
|
|
// activation occurs.)
|
|
//
|
|
// So this test is just making a note of the current behavior.
