--- Comment #3 from Fariborz Jahanian <fjahanian at apple.com> ---
This was recently fixed in in trunk.

% $CLANG -c test.m -Wno-objc-root-class
test.m:8:10: error: address of bit-field requested
  return &_name;
         ^~~~~~
1 error generated.

> Reduced test:
> 
> @interface CPIntVarI {
>   int _name:31;
> }
> @end
> 
> @implementation CPIntVarI
> - (int*)foo {
>   return &_name;
> }
> @end
> 
> Taking the address of a bitfield is obviously invalid, but clang shouldn't
> crash on it.
