[cfe-dev] Objective-C in `goto` label block.

I am testing `goto` with Objective-C (ARC enabled).
And I discovered Objective-C object cannot be exist under `goto` label.

				AA*	a1;			//	Fine.
				AA*	a2;			//	Compiler error: "Expected expression".

Anyway it's possible to put Objective-C object in nested block.

					AA*	a1	=	[AA new];

This makes me confused.

(1) Why Objective-C objects cannot be placed directly in label?
(2) Why it's possible in nested block?
(3) Is it designed or buggy behavior?

Can I know accurate behavior of `goto` and labels under Objective-C context?
