    No, you're not. Your problem is that you somehow got it into your head that you should be able to jump to some arbitrary label in the middle of a C function. Not even C code is allowed to do that, and for very good reason, too. And as if that wasn't enough, you presume to know what the internal symbol name of a label inside some function must be. Well, you presume incorrectly.

    In other words, the problem is that what you're trying to do makes no sense whatsoever, and the compiler is fully correct in rejecting your attempt.
