error[E0793]: reference to packed field is unaligned
--> $DIR/packed-struct-borrow-element-64bit.rs:13:15

LL | let brw = &foo.baz;

= note: packed structs are only aligned by one byte, and many modern architectures penalize unaligned field accesses
= note: creating a misaligned reference is undefined behavior (even if that reference is never dereferenced)
= help: copy the field contents to a local variable, or replace the reference with a raw pointer and use `read_unaligned`/`write_unaligned` (loads and stores via `*p` must be properly aligned even when using raw pointers)
error: aborting due to 1 previous error
