It happened because `zero_sized_map_values` used `layout_of` with types from type aliases, which is essentially the same as the ICE 4968.

// The cause is that `zero_sized_map_values` used `layout_of` with types from type aliases,

// Note that only type aliases with associated types caused the crash this time,

// not others such as trait impls.
