-Subject: [PATCH 67/68] Don't add to NULL in iterator.
-
-In C it is undefined to add anything to NULL. Clang recently began
-taking advantage of this and can assume that if anything is added or
-subtracted from a pointer that the pointer can be assumed non-NULL. The
-Address Sanitizer has been updated to report when this happens at
-runtime and produces messages like
-
-expat/lib/xmlparse.c:6509:23: runtime error: applying zero offset to null pointer
-SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior expat/lib/xmlparse.c:6509:23
-
-This can be mitigated with 'p ? p + n : NULL' which optimizes to just
-the add in all optimizing compilers, but avoids the undefined behavior.
