This is not an error, even strlen() from string.h doesn't check for NULL. The rationale behind this design decision is that you cannot check the length of something that doesn't exist.

These functions don't check for NULL because s != NULL is a pre-condition; if, for example, sdslen receives NULL as an argument, I'm pretty sure that it's caller's fault.
Also, making each and every function check for NULL hurts performance, as it causes many (unnecessary) branches.
