I often use gotos in C for error handling within a function. If you're allocating resources and something later on fails then you usually want (or need) to clean up those resources before returning. I've seen a lot of people duplicate the same cleanup code over and over again. I hate doing that. Goto makes it much cleaner. Just because you can make spaghetti with goto doesn't mean goto always has to make spaghetti. You do need to be careful though and assess any given situation carefully.
You can replace the goto with the correct use of setjmp(3) and longjmp(3). These are the exception handlers in C.
