Comment:

 This code in question is inside a #ifdef HAVE_FAST_UNALIGNED. Therefore
 means that your error is not a real error; you should
 [https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html#disabling-
 instrumentation-with-attribute-no-sanitize-undefined disable
 instrumentation] for this function and other functions that use
 HAVE_FAST_UNALIGNED (e.g. libavcodec/h2645_parse.c contains such a
 function).
