library/std/tests/slice-from-array-issue-113238.rs

// This intends to use the unsizing coercion from array to slice, but it only
// works if we resolve `<&[u8]>::from` as the reflexive `From<T> for T`. In
// #113238, we found that gimli had added its own `From<EndianSlice> for &[u8]`
// that affected all `std/backtrace` users.
