[PATCH] D67122: [UBSan][clang][compiler-rt] Applying non-zero offset to nullptr is undefined behaviour

[Dávid Bolvanský via Phabricator via cfe-commits]

xbolva00 added a comment.

&a[0] is really UB in C? Oh =[

Can we have clang warning also for this case? And suggest “a”?

Very common code, I think. Hopefully llvm’s optimizers do not exploit this case.
