[PATCH] D30283: [ubsan] Reduce alignment checking of C++ object pointers

[Eli Friedman via Phabricator via cfe-commits]

efriedma added a comment.

It's possible to misalign a global definition by misaligning its section with a linker script... but we can probably ignore that possibility.

It's very easy to misalign global declaration, though; for example:

a.c:

  extern int a[];
  int f(int x) { return a[x]; }

b.c:

  char a[] = "asdfzxcv";
