test "Crashes" {
    const cc = &[_]type{ S, S };
    const init = cc[0..1];
    const dd = init ++ [_]type{S};
}

A slight variation got a slightly different assert message:

Unreachable at D:\a\1\s\src\ir.cpp:28562 in buf_write_value_bytes. This is a bug in the Zig compiler.

That version used a const struct { field: type } instead of type directly, which may or may not be the cause of the difference.
