This fails to compile:

#[repr(C)]
struct Evil {
  x: u32,
  y: u16,
  should_be_an_offset_to_the_end_of_the_type: [Evil; 0],
}

This is #11924.

rust/src/librustc/ty/util.rs

Lines 705 to 709 in be88961

    
           // Fixed-length vectors. 
        
           // FIXME(#11924) Behavior undecided for zero-length vectors. 
        
           Array(ty, _) => { 
        
               is_type_structurally_recursive(tcx, sp, seen, representable_cache, ty) 
        
           }
