#[repr(packed)]
pub struct Bad<T: ?Sized> {
    data: T, //~ ERROR the size for values of type
}

fn main() {}
make accesses to fields of packed structs unsafe To handle packed structs with destructors (which you'll think are a rare case, but the `#[repr(packed)] struct Packed<T>(T);` pattern is ever-popular, which requires handling packed structs with destructors to avoid monomorphization-time errors), drops of subfields of packed structs should drop a local move of the field instead of the original one. cc #27060 - this should deal with that issue after codegen of drop glue is updated. The new errors need to be changed to future-compatibility warnings, but I'll rather do a crater run first with them as errors to assess the impact. 2017-09-27 11:23:45 +00:00			`#[repr(packed)]`
