[PATCH] D22227: [ubsan] Disable bounds-check for flexible array ivars

[Vedant Kumar via cfe-commits]

vsk added a comment.

The ivar list is set by all_declared_ivar_begin(), which accounts for ivars 
introduced by an implementation. Thanks for raising the point.

Consider this test:

  @interface HasFlexibleArray {
  @public char chars[0];
  }
  @implementation HasFlexibleArray {
  @public char chars2[0];
  }

I found that the current patch **will** sanitize accesses to 'chars', but 
**will not** sanitize accesses to 'chars2'. I think that's the desired behavior 
-- wdyt?
