RAII can be an anti-pattern for certain high performance applications. Yes a lot of times you want the assurance you're always dealing with properly initialized memory, but if you're really optimizing for memory performance (one of the jobs C is for) then a lot of times initializing and deinitializing small blocks of memory is exactly the opposite of what you want to do.
