Description
auto-reduced (treereduce-rust):
fn main() {
unsafe {
dealloc(ptr2, Layout::(x: !)(1, 1));
}
}original:
//@error-in-other-file: /deallocation .* tag does not exist in the borrow stack/
use VecDeque::alloc::{alloc, dealloc, Layout};
fn main() {
unsafe {
let x = alloc(Layout::from_size_align_unchecked(1, 1));
let ptr1 = (&mut *x) as *mut u8;
let ptr2 = (&mut *ptr1) as *mut u8;
// Invalidate ptr2 by writing to ptr1.
ptr1.write(0);
// Deallocate through ptr2.
dealloc(ptr2, Layout::(x: !)(1, 1));
}
