That's perfectly fine. That's not a problem caused UB, or involving UB.
Again, UB is a red herring.
It really isn't. Again, mindlessly parroting this doesn't give any substance to this claim. Please try to think about it for a second. For starters, do you believe it would make any difference if the C or C++ standard defined how the language should handle dereferencing a null pointer? I mean, in some platforms NULL is a tombstone, but on specific platforms NULL actually points to a valid memory address. The standards purposely leave this as undefined. Why is that? Seriously, think about it for a second.
It really isn't. It's a design choice that reflects the need to work with the widest possible range of platforms. The standards have already been updated with backwards-incompatible changes, but even the latest revisions purposely include UB.
I repeat: I see people mindlessly parroting nonsense about UB when they clearly have no idea what they're talking about.
