In C99 however, you are allowed to do &٭a because when the operand of & is the result of the unary ٭ operator

> neither that operator nor the & operator is evaluated and the result is as if both were omitted, except that the constraints on the operators still apply and the result is not an lvalue

For anyone who wants it, this is in section 6.5.3.2 Address and indirection operators, paragraph 3.
