| = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release! |
| = note: for more information, see issue #82523 <https://github.com/rust-lang/rust/issues/82523> |
| = note: fields of packed structs are not properly aligned, and creating a misaligned reference is undefined behavior (even if that reference is never dereferenced) |
| = note: this error originates in the macro `unaligned_references_external_crate::mac` (in Nightly builds, run with -Z macro-backtrace for more info) |
| |
| error: aborting due to previous error |
