Minimal repro: #[repr(packed)]
pub struct Foo {
bar: u8,
baa: [u32; 1],
}
const FOOMP: Foo = Foo {
bar: 0,
baa: [69; 1],
}; |

This doesn't repro on the playground where I did my other tests... ... but turns out playground has an outdated Miri. |
|
I tested it locally with the -Z flag, so it works for rustc ^^ |
|
Confirmed, and added a test. |
