| 22 | = note: fields of packed structs are not properly aligned, and creating a misaligned reference is undefined behavior (even if that reference is never dereferenced) | |
| 23 | = note: this error originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info) | |

| 25 | error: aborting due to previous error | |
